Tentative and pending both signal "not yet final," but they point in different directions. Pending names what you're waiting for. Tentative just reports that nothing is locked, without naming a specific blocker.
"Pending" points outward at a specific, identifiable awaited thing. "Tentative" points at the item's own unsettled status, with no single named condition holding it up.
Pending: a specific named blocker
This word always implies you can name exactly what's being waited on.
"The start date is pending the client's legal review."
There's one clear thing standing between now and confirmation, and the sentence names it.
Tentative: unsettled, nothing specific named
This word reports the same kind of uncertainty, but without pointing at a single cause.
"The start date is tentative -- we're still shaping the scope."
Nothing specific is being awaited here. The date just isn't locked yet, for reasons that may be several or unclear.

When you can actually name the blocker, "pending [X]" carries more information than "tentative" does -- it's usually the sharper choice.
Less informative: "The board approval is tentative." More informative: "The board approval is pending the Q3 financials."
If you know what you're waiting for, naming it is more useful to the reader than the vaguer "tentative."
A real grammatical difference
"Pending" works as a preposition, opening a clause. "Tentative" never does.
Correct: "Pending approval, we'll hold the build." Wrong: "*Tentative approval, we'll hold the build."
The second sentence is wrong -- "tentative" can't open a clause that way. "Tentative approval" works fine as a noun phrase ("we have tentative approval"), just not as a preposition-style opener the way "pending" can.
The rule
Ask whether you're waiting on an identified external event or decision, or whether the item is simply not yet committed with nothing specific to point to. If you can name the blocker, "pending [X]" is usually the sharper, more informative choice. If nothing specific is being awaited, use "tentative" -- and remember it can't open a clause the way "pending" can.
Practice scenarios
Practice choosing between tentative and pending in situations like:
- naming a specific approval you're waiting on versus describing general unsettled status
- upgrading a vague "tentative" status to a more informative "pending [X]"
- catching the preposition error ("*Tentative approval, we'll proceed")
Useful practice phrases:
- "The start date is pending the client's legal review."
- "The start date is tentative -- we're still shaping the scope."
- "Pending approval, we'll hold the build." (never "Tentative approval, we'll hold the build")
If you can name what you're waiting for, pending says more. If you can't, tentative is the honest choice.
