Concept

An idiom is a fixed expression whose overall meaning cannot be worked out from the separate meanings of its words. To substitute an idiom, the replacement must carry the same sense as the idiom and must fit the grammar and tense of the sentence — matching meaning, not merely tone or register.

The idiom "come in handy" means "to be useful or serviceable at the moment it is needed"; its past-tense form is "came in handy".

Application

1. Read the sentence: "Parvathy’s experience in marketing came in handy during the product launch." The underlined segment reports what her marketing experience did for her at the launch.

2. Apply the idiom’s meaning: her marketing experience proved useful — it produced a practical advantage — exactly when it was needed.

3. Choose the replacement that carries that same sense and keeps the past-tense frame: "turned out to be beneficial", where "beneficial" means advantageous or helpful.

4. Substitute and reread: "Parvathy’s experience in marketing turned out to be beneficial during the product launch." Both the meaning and the grammar of the original sentence are preserved.

Contrast

• "turned out to be boring" — "boring" reports a lack of interest, an entirely different axis from usefulness.

• "turned out to be innovative" — "innovative" reports novelty of method; an idea can be new without being useful, so this does not carry the idiom’s sense.

• "turned out to be useless" — "useless" reports the lack of practical value, reversing the sense of the idiom.

Hence the underlined segment "came in handy" is best substituted by "turned out to be beneficial".
