Suffixes -ary and -ery
a suffix occurring originally in loanwords from Classical and Medieval Latin, on adjectives (elementary; honorary; stationary; tributary), personal nouns (actuary; notary; secretary), or nouns denoting objects, especially receptacles or places (library; rosary; glossary). The suffix has the general sense “pertaining to, connected with” the referent named by the base; it is productive in English, sometimes with the additional senses “contributing to,” “for the purpose of,” and usually forming adjectives:
complimentary; visionary; revolutionary; inflationary.
a suffix of nouns denoting occupation, business, calling or condition, place or establishment, goods or products, things collectively, qualities, actions, etc.:
archery; bakery; cutlery; fishery; trickery; witchery.
Be very careful when spelling our suffixes with some words, for example:
What does each mean?
