Vzorec užití:
rotary [machine / part / motion]

rotating (Very close in meaning; more general and used both before and after nouns, while 'rotary' is mostly used before nouns in technical or specific descriptions.)
|
revolving (Emphasizes continuous turning around something; often used for doors, stages, or mechanisms, while 'rotary' sounds more technical and mechanical.)
Antonyma
stationary (Describes something that does not move or turn, the opposite of a part or motion that is rotary.)

Vzorec užití:

Častá chyba:

Synonyma
roundabout (The more common general-English term internationally; 'rotary' is mainly regional in parts of the US.)
|
traffic circle (A US term for the same kind of circular junction; similar meaning, but 'rotary' is especially tied to New England usage.)

Vzorec užití:

Learners sometimes write this as a common noun ('a rotary') even when referring to the organization; in practice it is almost always capitalized ('Rotary') and often appears as 'Rotary Club'. It is unrelated in meaning to 'rotary phone' or 'rotary motion'.
Synonyma
service club (A more general term for volunteer organizations that do charity and community projects; 'Rotary' is one specific international organization of this kind.)
