Additional Information

think ← Old English þyncan.
thought ← Old English þohte , preterite of þencan.

Etymology

O.E. þencan "conceive in the mind, think, consider, intend" (past tense þohte, p.p. geþoht), probably originally "cause to appear to oneself," from P.Gmc. *thankjan (cf. O.Fris. thinka, O.S. thenkian, O.H.G. denchen, Ger. denken, O.N. þekkja, Goth. þagkjan); O.E. þencan is the causative form of the distinct O.E. verb þyncan "to seem or appear" (past tense þuhte, pp. geþuht), from P.Gmc. *thunkjan (cf. Ger. dünken, däuchte). Both are from PIE *tong- "to think, feel" which also is the root of thought and thank. The two meanings converged in M.E. and þyncan "to seem" was absorbed, except for archaic methinks "it seems to me." Jocular pp. thunk (not historical, but by analogy of drink, sink, etc.) is recorded from 1876. Think-tank is 1959 as "research institute" (first ref. is to Center for Behavioral Sciences, Palo Alto, Calif.); it had been colloquial for "the brain" since 1905.
