When added to verbs, -er1 forms nouns denoting a person, animal or thing that performs or is used in performing the action of the verb ( baker; eye-opener; fertilizer; pointer; teacher).
Compare -ier 1, -yer.[Middle English -er(e), representing Old English -ere agentive suffix (c. Old High German -āri, Gothic -areis < Germanic *-arjaz < Latin -ārius -ary) and Old English -ware, forming ethnonyms (as Rōmware Romans), c. Old High German -āri < Germanic *-warioz people]
-er2
, a noun suffix occurring in loanwords from French in the Middle English period, most often names of occupations (butcher; carpenter; grocer; mariner; officer), but also other nouns (corner; danger; primer).
[Middle English < Anglo-French -er, Old French -ier < Latin -ārius, -ārium. compare -ary, -eer, -ier2]
-er3
, a termination of nouns denoting action or process, occurring orig. and predominantly in loanwords from French or Anglo-French: dinner; rejoinder; remainder.
[< Anglo-French or Old French, orig. infinitive suffix -er, -re]
-er4

[Middle English -er(e), -re, Old English -ra, -re; c. German -er]
-er5

[Middle English -er(e), -re, Old English -or; c. Old High German -or]
-er6
, a formative appearing in verbs having frequentative meaning: flicker; flutter; shiver; shudder.
[Middle English; Old English -r-; c. German -(e)r-]
-er7
, Chiefly Brit. a suffix that creates informal or jocular mutations of more neutral words, which are typically clipped to a single syllable before application of the suffix, and sometimes subjected to other phonetic alterations: bed-sitter; fresher; rugger; soccer. Compare -ers.
[probably modeled on nonagentive uses of -er1; said to have first become current in University College, Oxford, 1875–80]
