picnicker

The word 'picnicker' is a modern English agent noun derived from the activity 'picnic'. The term 'picnic' itself entered English from French 'pique-nique' in the mid-18th century, originally referring to a social gathering where each participant contributed a share of food. The French term's own origins are obscure but may be based on 'piquer' (to pick) and a nonsense rhyming syllable 'nique'. The suffix '-er', of Germanic origin via Old English '-ere', is one of the most productive agent-noun suffixes in English, attaching to verbs and nouns to denote a person involved in an activity. Thus, the literal construction 'picnic-er' transparently means 'one who picnics', following a common English pattern for describing participants in an activity, such as 'hiker' or 'painter'.
