In a standup, an engineer says: "___ , we disabled that flag last sprint because it was causing timeouts, but I'd double-check the changelog." Which phrase best signals a recollection offered with a hint of uncertainty?
If memory serves is a fixed idiom meaning "if I recall correctly." It uses the singular verb "serves" with uncountable "memory" and no article. "If memory serve" drops the required "-s," "if the memory serves" wrongly adds an article, and "if memories serve" wrongly pluralizes "memory."
2 / 10
Which sentence uses "if memory serves" correctly?
"If memory serves, this endpoint was deprecated back in version 3.2, though it's worth confirming" correctly hedges a claim about the past that the speaker isn't fully certain of. It cannot introduce a confident future plan, an instruction, or a scheduled future event.
3 / 10
Fill the blank: "___ , the original design doc proposed a queue-based architecture before we switched to synchronous calls."
If memory serves has a fixed word order: "if" + "memory" + "serves." The other options scramble this into invalid, meaningless sequences.
4 / 10
Which pair correctly distinguishes "if memory serves" from "I'm certain that"?
"If memory serves, the bug was in the retry logic" leaves room for being wrong. "I'm certain the bug was in the retry logic" claims full confidence. Swapping one for the other changes how reliable the claim sounds.
5 / 10
A postmortem reads: "___ , this same incident happened about a year ago, though I'd want someone to confirm against the incident log." Which best completes the sentence?
If memory serves is the correct, fixed form. The other options scramble the required word order into invalid phrases.
6 / 10
Which sentence contains an error in the use of "if memory serves"?
"If memory serves that I have about last quarter, the outage lasted six hours" incorrectly attaches a relative clause to the fixed idiom, which cannot be modified this way. The other three sentences use it correctly as a standalone hedge before a recollected fact.
7 / 10
Choose the sentence where "if memory serves" is best replaced by "if I recall correctly" without changing the meaning.
"If I recall correctly, this library had a known memory leak in versions before 2.0" preserves the meaning exactly. The other options misuse the phrase as an urgency marker, an unrelated construction, or a pairing with a specific future date.
8 / 10
A code review comment reads: "___ , we settled on this naming convention after a long debate in the RFC thread — worth checking if you want the full context." Which best fits?
If memory serves is the correct, standard form — "memory" stays uncountable/singular and "serves" keeps its "-s" ending. Option A wrongly pluralizes "memory." Option B drops the required "-s." Option D wrongly adds "the" and drops the "-s."
9 / 10
Which register note about "if memory serves" is accurate?
"If memory serves" works equally well in a spoken standup ("If memory serves, that test was already flaky") and a written postmortem. It always signals a recollection the speaker isn't 100% certain of.
10 / 10
Which sentence best demonstrates "if memory serves" hedging a claim about a past technical decision?
"If memory serves, we chose to shard the database by customer ID rather than by region..." is the textbook use: a plausible but not fully certain recollection of a past technical decision. The other options misuse the phrase as a command intensifier, insert it awkwardly mid-clause, or pair it incorrectly with a future date.
