Collocation and register – choose the noun that fits "give their _____ to" Complete the sentence with the most appropriate word: "Her parents will never give their ______ to so much an unsuitable match." Select the noun that most naturally completes the idiomatic phrase.

Given data

• We need the noun that collocates with "give their ____ to".
• Sentence has a slightly awkward phrase "so much an unsuitable match"; idiomatically this is "so unsuitable a match", but the blank choice is unaffected.

Concept/Approach
The standard collocation is give consent to (formal permission). Parents "give their consent to" a marriage.

Option analysis
consent — correct and most formal/idiomatic: "give their consent to …." ✅assent — also means agreement/approval, but "give assent to" is used more in legislative/official contexts and less with family approval of a match.approval — possible ("give their approval to"), but the most set phrase with give their is "consent".agreement — usually "reach an agreement" rather than "give agreement to".

Common pitfalls

• Confusing assent (express agreement) with consent (permission).

Final Answer
consent
