TOEIC Link Part 5: coarse versus course
Coarse and course are pronounced identically, yet they belong to different parts of speech. Coarse is an adjective meaning rough in texture, or rude and unrefined in manner. Course is a noun meaning a route, a series of lessons, a part of a meal, or a direction of action. Part 5 puts one into a sentence where the sound gives nothing away, so it checks whether you need a describing word or a naming word. For the wider set of look-alike traps, start with the commonly confused word pairs master index.
The core rule: describing versus naming
- coarse = rough in texture, or crude in manner (adjective). The fabric felt coarse against the skin. / His coarse remarks embarrassed the team. It answers what kind? — rough. Link coarse to rough and crude: it always describes a noun, never stands alone as a thing.
- course = a route, a class, a dish, or a plan of action (noun). She enrolled in a project management course. / The ship changed course to avoid the storm. / The main course was served after the soup. It answers which thing? — the route, class, or dish. Link course to class and route: it names something.
The extra letters carry the clue: course has the -ou- of route and journey, both about paths you follow; coarse shares its -oa- with rough-sounding words and stays an adjective. If the blank needs a describing word, it is coarse; if it needs a noun, it is course.
Why Part 5 likes this pair
Because the two words sound the same, only grammar and meaning separate them. If the blank describes how something feels or behaves, you need coarse. If the blank names a route, a class, or a dish, you need course.
The sandpaper had a __ surface that scratched the wood.
A describing word for rough texture needs coarse.
All new hires must complete a safety __ before starting.
A word naming a series of lessons needs course.
Spotting the clue
Decide whether the blank is an adjective or a noun:
- Does the blank describe a noun (a surface, a manner, a grain)? → choose coarse (coarse sand, coarse language).
- Does the blank name a thing you take, follow, or serve? → choose course (a training course, off course, the second course).
A quick test: can you put a noun right after it, as in coarse cloth? Then it is the adjective coarse. Can you put a or the in front and have it stand as a thing, as in the course? Then it is the noun course. Watch the fixed phrases: course appears in of course, in due course, on course, and course of action, while coarse appears in coarse-grained and coarse language. Because this pair mixes texture with routes, it sits alongside the other traps in the sound-alike verb pairs study guide.
Common Part 5 patterns
- Fixed expressions almost always want course: of course, in due course, a course of action, stay on course.
- Anything describing texture or manner wants coarse: coarse salt, coarse fibres, coarse jokes.
- Business training contexts want course: an online course, complete the course, course materials.
If the blank sits before a noun and tells you what kind, choose coarse. If the blank is the noun — a route, a class, a dish, a plan — choose course.
Quick recap
- Coarse = rough or crude (adjective) — it describes.
- Course = route, class, dish, or plan (noun) — it names.
- Part 5 test: describing word → coarse; naming word → course (and every of course is spelled with the -ou-).
