1
student in a specific school grade
A student who is in a certain school grade, usually in the U.S. (for example, a third grader is in third grade).
Vzorec užití:
a [number]th grader
Častá chyba:
Learners sometimes say *"a grade three student"* when using American English, where *"a third grader"* is more natural. Also, *grader* in this sense is almost always used with a number or level (e.g., *first grader*, *tenth grader*), not alone. In British English, people usually say *Year 3 pupil* or *student in Year 3*, not *third grader*.
Synonyma
student (A general word for someone who studies at a school or university; it does not show which grade they are in.)
|
pupil (Common in British English for a child at school; like 'student', it does not show the exact grade.)
Antonyma
teacher (In a school setting, the teacher is the adult who teaches the class, not a member of the grade.)

person who marks student work
A person who reads tests or papers and gives a score or grade to them.
Vzorec užití:
[someone] is the grader for [test/work]
Častá chyba:
Learners sometimes think *grader* always means a school child because of phrases like *"fifth grader"*. In education contexts, *grader* can also be the person who scores exams. Context (who is doing the work vs. who is scoring it) helps distinguish the meanings.
Synonyma
marker (Used mainly in British and academic contexts; focuses on the act of marking scripts, not on classroom teaching.)
|
examiner (More formal; often someone who designs or officially oversees exams as well as marking them.)
Antonyma
test taker (The person who sits the exam is the opposite role to the grader, who scores it.)

road construction vehicle with blade
A big machine with a long blade that makes the ground or road flat and smooth.
Vzorec užití:
a grader levels [a surface/road]
Častá chyba:
Learners may confuse a *grader* with other construction machines like a *bulldozer* or *excavator*. A grader is recognized by its long central blade and is mainly used for leveling, not for heavy pushing or deep digging.
Synonyma
road grader (A more specific term that clearly shows the machine is used for road work.)
Antonyma
excavator (An excavator mainly digs and removes earth, while a grader mainly levels and smooths surfaces.)

machine/person sorting items by grade
A person or a machine that separates things, like fruit or wood, into groups by size or quality.
Vzorec užití:
a grader sorts [items] by [size/quality]
Častá chyba:
Because *grade* often relates to school, learners may not realize that *grader* can also refer to machines and workers that sort products by quality. Context with products like fruit, eggs, or wood signals this industrial meaning.
Synonyma
sorter (A more general word for something that separates items into groups; it does not always suggest an official quality grade.)
|
classifier (More formal and technical; used especially in industrial and scientific contexts.)
Antonyma
mixer (A machine or person that combines different items together, doing the opposite of separating them by grade.)
