"Walk back it" is a common and visible ESL error, and it's worth a dedicated correction because the fix isn't intuitive from the grammar of similar-looking verbs.
"Walk back" is a separable phrasal verb. With a full noun object, both the joined and split forms work: "walk back the claim" and "walk the claim back" are both natural. But with a pronoun object, only the split form is correct: "walk it back," never "walk back it."
Right and wrong, side by side
Wrong: "The claim didn't hold up, so we had to walk back it." Right: "The claim didn't hold up, so we had to walk it back."
Correct with a full noun object, either order: "We had to walk back the claim." / "We had to walk the claim back."
A second, related trap: the missing preposition
Learners transferring the pattern from "backtrack on," "renege on," or "go back on" often add "on" to "walk back" by analogy. "Walk back" doesn't take "on," ever -- not with a pronoun, and not with a full noun object either.

Start learning for free →Wrong: "The company walked back on the claim." Right: "The company walked back the claim." (or, naming the stance rather than the statement: "The company walked back from its earlier position.")
Note that "walk back from" is a different, correct pattern -- it names the stance being retreated from, rather than the specific statement being retracted. It's "walked back on the claim" specifically that's wrong.
Why these particular slips are easy to make
English has plenty of verbs that pair naturally with "on" for this kind of retreat -- "backtrack on," "renege on," "go back on a promise" all take it. "Walk back" looks like it belongs to that family, but it doesn't. And most separable phrasal verbs ("turn it off," "pick it up") already require the split form with a pronoun, so the "walk back it" error usually comes from treating "walk back" as if it worked like a single, non-separable verb instead.
A simple test to check your own sentence
Before sending an update, check two things: if the object is a pronoun ("it," "this," "that"), it must sit between "walk" and "back" -- never after "back." And "walk back" never takes "on," regardless of what the object is. If your sentence passes both checks, the grammar is sound.
Practice scenarios
Practice using walk back in situations like:
- rewriting a pronoun-object sentence into the correct split form
- catching a colleague's draft that adds "on" after "walk back"
- choosing between "walk back the claim" and "walk back from the position"
Useful practice phrases:
- "The claim didn't hold up, so we had to walk it back."
- "We had to walk back the claim." / "We had to walk the claim back."
- "The company walked back from its earlier position."
Pronoun goes in the middle. "On" doesn't belong anywhere in the sentence at all.
