The most useful IELTS General Training letter vocabulary is not a collection of impressive openings. It is language that makes your purpose, relationship, and requested outcome unmistakable.
IELTS officially describes Writing Task 1 as a response of at least 150 words to an everyday situation, normally written in about 20 minutes. The prompt identifies three points to cover. Depending on the reader, the letter may be personal, semi-formal, or formal. You do not need to write addresses, and the answer must be connected text rather than notes or bullet points.
That makes vocabulary a set of decisions. Are you reporting a broad complaint or a formal grievance? Do you want a measure to alleviate a problem rather than promise to eliminate it? Is your request genuinely feasible under the stated constraints? Are you asking someone to follow through on an earlier commitment?
| Expression | Letter job | Boundary |
|---|---|---|
| grievance | name a formally raised workplace concern | not every complaint is a grievance |
| alleviate | request a reduction in a problem or pressure | not a promise of removal |
| feasible | test whether an action can be carried out in practice | not automatically desirable or approved |
| follow through on | request completion of an earlier promise or plan | not merely contact someone again |
Start from purpose and relationship
Before choosing a phrase, identify two facts.
First, what must this letter accomplish: ask, complain, apologise, explain, arrange, or combine several of these? Second, who is the reader? Dear Sam permits warmer and more conversational wording than Dear Sir or Madam. A manager you know may call for semi-formal language between those points.
Do not turn those categories into three fixed templates. The prompt, not a memorized label, determines the tone. A complaint to a close friend may remain tactful and direct. A formal request can be warm without sounding casual. Appropriate style comes from the whole message: greeting, verb choices, degree of directness, explanation, and closing.
Requests: make the action and constraint visible
A useful request says what you want and why it is workable.
"Would it be feasible to move the inspection to Thursday afternoon? I can provide access from 2 p.m. onward."
Feasible means capable of being done in practice under the relevant constraints. The frame feasible within the available time/budget is useful when a request depends on real limits. It does not mean the action has been approved, is profitable, or is the best choice.
Compare:
"I would be grateful if you could change the date."
"Would it be feasible to change the date without delaying the repair?"
The first is a courteous request. The second asks the reader to judge practicality under a named condition. Both can be appropriate; the longer word earns its place only in the second job.
Avoid demanding language unless the relationship and facts support it. You must immediately... may sound disproportionate when Could you please... or I would appreciate it if... states the request clearly. Equally, excessive softening can hide the action: after one courteous frame, name exactly what you need.
Complaints: separate the problem from the remedy
In ordinary correspondence, complaint is usually the broad term. A grievance often signals that a workplace concern has entered, or is being discussed under, a named formal procedure. Procedures vary by organisation and jurisdiction, and raising a grievance does not prove the allegation.
"I am writing to make a complaint about repeated overnight noise."
"I am writing to confirm that I have raised a formal grievance under the organisation's published procedure."
Do not upgrade any dissatisfaction into a grievance merely because the word sounds formal. Use the narrower term only when the prompt supplies procedural facts. In other cases, complaint, concern, or problem is accurate.
After naming the issue, describe its effect and the requested remedy:
"The heating has failed on three evenings this week, leaving the room unusably cold. I would therefore appreciate an inspection by Friday."
This sequence is stronger than a paragraph of emotional adjectives. The dates and consequences establish the complaint; the final sentence identifies a realistic response.
Ask for reduction without promising a cure
Alleviate + object means make pain, pressure, hardship, or another bad condition less severe. It is transitive: alleviate the disruption, not alleviate from the disruption.
"A temporary study room would help alleviate the disruption while the heating is repaired."
The room reduces the difficulty; it does not fix the heating. That boundary is valuable in complaint and arrangement letters because a temporary measure and a full remedy are not the same thing.
Mitigate, relieve, and ease overlap with alleviate in many contexts, so do not manufacture a rigid distinction. The reliable contrast is with an unsupported total claim. If the measure only reduces inconvenience, do not say it eliminates the problem.
Understanding is only the first step.
Lyra Practice helps you retrieve and use high-value workplace expressions in realistic situations until they feel natural.
Start a practice session →Apologies: own the action, then repair it
A functional apology has three parts:
- a direct acknowledgement;
- a proportionate explanation, not an excuse;
- a concrete next action.
"I apologise for missing our appointment on Tuesday. An unexpected timetable change meant that I recorded the wrong time. I have now updated the booking and can meet at any point on Friday afternoon."
Vocabulary cannot replace ownership. Please accept my sincerest apologies for any inconvenience that may have been caused is vague if the writer plainly caused a specific problem. Name it: I apologise for returning the keys two days late. Then show the repair.
If you made an earlier promise, follow through on + noun identifies the commitment-to-action link:
"I am sorry that I did not follow through on my promise to send the documents on Monday. I have attached them to this message."
The expression highlights action required after a promise, intention, or start. It does not merely mean follow up on, which can refer to seeking information or making another contact. Its progressive form also does not guarantee completion: I am following through on the arrangement describes action underway.
Explanations: give enough cause, not a defensive history
An explanation should make the situation intelligible and support the requested outcome. It should not consume the letter.
"Because my evening shift now ends at 10 p.m., the current checkout time is no longer feasible. I am therefore asking whether I may return the equipment the following morning."
The cause and request are connected. The letter does not need every detail of the work schedule.
When the cause is sensitive or uncertain, calibrate it: partly because, appears to have resulted from, or may have been caused by. Do not present speculation about another person's motive as fact. The delay may have resulted from a booking error is safer than Your staff deliberately ignored my request when the evidence does not establish intent.
Arrangements: specify time, responsibility, and fallback
Arrangement language should answer three questions: who will act, when, and what happens if the first option fails?
"I can collect the package between 4 and 6 p.m. on Wednesday. If that is not feasible, please leave it with the reception desk and let me know by email."
"Could you confirm who will follow through on the repair request and when I should expect an update?"
Avoid as soon as possible when a date matters. Avoid at your convenience when the situation is urgent. Courteous language and operational precision can coexist.
Closings should match the actual next step
A closing is more useful when it names the response you need.
- Request: I would appreciate confirmation by Thursday.
- Complaint: I look forward to your proposed solution.
- Apology: Thank you for your patience, and I will ensure the keys arrive on Friday.
- Arrangement: Please let me know which of the two times is feasible.
For a personal letter, a warmer close such as I hope we can arrange this soon may fit. Formal correspondence often uses Yours sincerely when the person is named and Yours faithfully with Dear Sir or Madam in British convention, but the entire letter's consistency matters more than inserting a closing into otherwise mismatched prose.
A worked Task 1 letter
Situation: You arranged for a landlord to repair a leaking window, but nobody arrived. Write to the property manager. Explain the problem, describe its effect, and say what you want done.
Dear Ms Patel,
I am writing about the window repair scheduled for Tuesday morning. Although I remained at home during the agreed period, nobody arrived and I received no message explaining the delay.
Rain is continuing to enter around the frame and has damaged the paint below it. Moving the desk has alleviated the immediate risk to my computer, but it has not addressed the leak. I would therefore be grateful if you could arrange another inspection before Friday.
Could you also confirm who will follow through on the repair after the inspection? I am available after 3 p.m. on Thursday or throughout Friday morning. If neither time is feasible, please suggest an appointment early next week and provide at least one day's notice.
I look forward to your confirmation.
Yours sincerely, Alex Morgan
The letter covers all three points, keeps reduction distinct from repair, and turns dissatisfaction into a precise request. It does not call the issue a grievance because no formal workplace procedure is involved.
Quick check
1. An employee has invoked a named formal workplace procedure. Which noun fits that stated fact?
A. inconvenience
B. grievance
C. arrangement
2. Which sentence asks about practical possibility without implying approval?
A. "Would it be feasible to complete the work within two days?"
B. "The work is feasible, so it is definitely authorised."
C. "Would it feasible completing the work?"
3. A temporary room reduces disruption but the original problem remains. It may:
A. alleviate the disruption
B. alleviate from the disruption
C. eliminate every cause
4. Which phrase highlights completing an earlier commitment?
A. follow through on the promised refund
B. follow the refund through on
C. follow through the refund
Answers: 1-B, 2-A, 3-A, 4-A. A grievance is procedural in the supplied workplace facts. Feasible concerns practicability. Alleviate takes a direct object and permits residual difficulty. Follow through on preserves the commitment-to-action pattern.
Controlled practice
Write a 150–190 word letter to a course administrator. A timetable change prevents you from attending one session; explain the problem, request another arrangement, and propose two times.
Before drafting, decide:
- whether complaint or grievance is justified by the facts;
- which option is feasible under your schedule;
- what temporary step could alleviate the difficulty;
- what earlier promise, if any, someone must follow through on.
Use only the expressions whose jobs genuinely occur. A good letter may need two and reject two.
