TOEIC Link Part 5: sensible versus sensitive

Sensible and sensitive grow from the same root — sense — but they describe very different qualities. Sensible means showing good judgment, practical, reasonable; sensitive means easily affected, delicate, or quick to respond to feelings or stimuli. Because both are adjectives that can sit in the same blank, Part 5 forces you to read the whole sentence for meaning rather than guess by the shared root. For another adjective pair built on a shared stem, see economic versus economical.

The core rule: good judgment versus easily affected

• sensible (adjective) = practical, reasonable, showing good sense. It was a sensible decision to confirm the budget first. / Wear sensible shoes for the factory tour.
• sensitive (adjective) = easily affected, delicate, or responsive to feelings, light, or data. This is a sensitive topic, so handle it carefully. / The instrument is sensitive to temperature changes.

The memory hook: a sensible person uses common sense to act wisely, while a sensitive person or device senses and reacts to small changes. One is about judgment; the other is about reaction.

Why Part 5 likes this pair

Both words are adjectives, so grammar alone will not decide the blank — the meaning of the surrounding clause must.

Given the cost, it was a __ choice to lease rather than buy.

A leasing decision based on cost is a practical, well-judged one, so the answer is sensible.

The report contains __ financial data that must not be shared externally.

Data that must be protected is delicate and confidential, so the answer is sensitive.

Spotting the clue in the structure

Ask what quality the sentence is praising or warning about:

• It points to practicality, reason, or good judgment (a sensible plan, a sensible amount, sensible precautions) → choose sensible.
• It points to delicacy, confidentiality, or reactivity (sensitive information, sensitive skin, sensitive to criticism, a sensitive sensor) → choose sensitive.

Watch for collocations the test reuses: sensitive information, sensitive issue, and sensitive equipment are fixed phrases that almost never take sensible. Likewise a sensible decision and sensible precautions rarely take sensitive. For another pair where one word signals caution and discretion, see discreet versus discrete.

Quick self-check

1. Negotiations broke down because the manager raised a politically __ subject. (sensitive — delicate, easily causing reaction)
2. Setting aside an emergency fund is a __ habit for any business. (sensible — practical and wise)

Takeaway

If the sentence rewards practicality, reason, or good judgment, choose sensible. If it points to something delicate, confidential, or quick to react, choose sensitive. The shared root sense is the trap; let the meaning of the clause — wise action versus easy reaction — settle the answer.
