TOEIC Link Part 5: personal versus personnel

Personal and personnel look like twins on the page, but they are different parts of speech with different stress and different jobs. Personal is an adjective meaning private or belonging to one individual; personnel is a noun meaning the people employed by an organization. Because office passages constantly mention staff, records, and departments, Part 5 can drop either word into a blank and let the careless reader pick by sound. For another office pair separated by a single letter, see compliment versus complement.

The core rule: adjective versus noun

• personal (adjective, stress on PER-son-al) = private, individual, belonging to a particular person. Please keep your personal belongings with you. / She shared her personal opinion.
• personnel (noun, stress on per-son-NEL) = the staff of a company; the workforce. All personnel must complete the training. / The personnel department reviewed the applications.

Two clues separate them. First, the extra n and the -nel ending mark the noun: personnel ends like the word hote_l, and it names a group of people. Second, the stress moves to the end in personnel, while personal keeps its stress at the front.

Why Part 5 likes this pair

The two words occupy different grammatical slots, so the surrounding sentence almost always tells you which one fits — if you read for part of speech rather than sound.

Only authorized __ may enter the server room.

The blank is the subject — a group of people who may enter — so the noun personnel is required. Personal is an adjective and cannot stand alone as the subject here.

The form asks for your __ contact information.

Here the blank modifies the noun information, so an adjective is needed: personal.

Spotting the clue in the structure

Ask what the blank is doing in the sentence:

• It describes a noun (personal details, personal opinion, personal use) → choose the adjective personal.
• It is a noun, often the subject or object, naming staff (qualified personnel, personnel records, military personnel) → choose personnel.

Note the common phrase personnel records versus personal records: personnel records are the company's files on its employees, while personal records are an individual's own private files. Part 5 can exploit exactly that contrast, so let the meaning of the whole sentence decide. For another pair where part of speech and one letter settle the answer, see council versus counsel.

Quick self-check

1. The company hired additional __ to handle the seasonal demand. (personnel — a group of staff; the noun is needed)
2. Employees may not use the office printer for __ projects. (personal — the adjective modifying projects)

Takeaway

If the blank names the staff of an organization, you need the noun personnel, with its extra n, its -nel ending, and its stress on the last syllable. If the blank describes something as private or individual, you need the adjective personal. Read for part of speech first, confirm with meaning, and the one-letter gap stops being a trap.
