前綴contra-,contro-,countrer-

漢：contra來源於拉丁語，意爲"against,contrary,opposite"。contro,counter是它的變形。前綴contra-原是拉丁介詞，意思爲against 或opposite,它主要出現在直接引進英語的拉丁詞中，是個衹與拉丁詞根綴郃的原生詞綴。但是與contra-綴郃的詞基恰好是英語中的拉丁借詞，在這種情況下，也可以把它看作派生詞綴。

英：word-forming element meaning "against, in opposition," from Latin adverb and preposition contra (see contra). The Latin word was used as a prefix in Late Latin. In French, it became contre- and passed into English as counter-. The Old English equivalent was wiðer (surviving in withers and widdershins), from wið "with, against."
