The state or quality of being a component; the characteristic of being a constituent part of something larger.
From 'component' (Latin 'componens,' meaning 'putting together,' from 'componere' 'to put together') + '-cy' (suffix forming nouns of state or condition, as in 'urgency'). This is a formal technical term.
The '-cy' suffix is fading from modern English—we rarely coin new words with it anymore—but it survives in older formal terms like 'urgency,' 'fluency,' and this technical 'componency.'
