intellect: [14] Intellect and intelligent come from the same ultimate source: Latin intelligere ‘perceive, choose between’. This was a compound verb formed from the prefix inter- ‘between’ and legere ‘gather, choose, read’ (source of English lecture, legible, etc). Its past participle intellectus came to be used as a noun meaning ‘perception, comprehension’, which English acquired as intellect via Old French; while its present participle intelligēns gave English intelligent [16].

The derivative intelligentsia [20] was borrowed from Russian intelligyentsia, which in turn came via Polish inteligiencja from Latin intelligentia ‘intelligence’.
