father & mother 這兩個單字的由來?

Question

請問有人知道：
father & mother 這兩個單字的由來嗎?

字首fa & mo 有什麼涵義嗎?

你好：謝謝你的回答，我看的不是很懂，各國的發音都好像很類似，是從嬰兒語PA而變成FA的嗎? 那MO呢?
P.Gmc 、PIE 是什麼意思呢? 真的很對不起，我應該用更多點數的。

Answer 1

以下是這兩個字的字源，皆是古英語。
Father - - O.E. fder, from P.Gmc. *fader (cf. O.N. fair, Ger. vater), from PIE *p@ter (cf. Skt. pitar-, Gk. pater, L. pater, O.Pers. pita, O.Ir. athir "father"), presumably from baby-speak sound like pa. The classic example of Grimm's Law, where PIE "p-" becomes Gmc. "f-." Spelling with -th- (16c.) reflects widespread phonetic shift in M.E. that turned -der to -ther in many words; spelling caught up to pronunciation in 1500s
Mother - - O.E. modor, from P.Gmc. *mothr (cf. O.S. modar, Dan. moder, Du. moeder, Ger. Mutter), from PIE *mater- (cf. L. mater, O.Ir. mathir, Lith. mote, Skt. matar-, Gk. meter, O.C.S. mati). Spelling with -th- dates from early 16c., though that pronunciation is probably older.
O.E.: Old English
