teach

teach: [OE] To teach someone is etymologically to ‘show’ them something. The word goes back ultimately to the prehistoric Indo-European base *deik- ‘show’, which also produced Greek deiknúnai ‘show’ (source of English paradigm [15]) and Latin dīcere ‘say’ (source of English diction, dictionary, etc). Its Germanic descendant was *taik-, which produced English token and German zeigen ‘show’. From it was derived the verb *taikjan, ancestor of English teach.

teach (v.)

Old English t?can (past tense t?hte, past participle t?ht) "to show, point out, declare, demonstrate," also "to give instruction, train, assign, direct; warn; persuade," from Proto-Germanic *taikijan "to show" (cognates: Old High German zihan, German zeihen "to accuse," Gothic ga-teihan "to announce"), from PIE *deik- "to show, point out" (see diction). Related to Old English tacen, tacn "sign, mark" (see token). Related: Taught; teaching.

Chico: you don't have to teach me, I know how. [kicks him]

The usual sense of Old English t?can was "show, declare, warn, persuade" (compare German zeigen "to show," from the same root); while the Old English word for "to teach, instruct, guide" was more commonly l?ran, source of modern learn and lore.
