междометие [используется в разговорной речи]; сокращение от (I have) got you; то же, что и gotcher понятно Например: "You might try for a record of her blood type first..." Wilks sighed. "I gotcha." (H. Waugh) — "Ты мог бы сначала выяснить её группу крови". Уилкс вздохнул. "Я тебя понял".
noun Etymology: alteration of got you an unexpected usually disconcerting challenge, revelation, or catch; also an attempt to embarrass, expose, or disgrace someone (as a politician) with a gotcha
A misfeature of a system, especially a programming language or environment, that tends to breed bugs or mistakes because it both enticingly easy to invoke and completely unexpected and/or unreasonable in its outcome. For example, a classic gotcha in C is the fact that if (a=b) {code;} is syntactically valid and sometimes even correct. It puts the value of "b" into "a" and then executes "code" if "a" is non-zero. What the programmer probably meant was if (a==b) {code;} which executes "code" if "a" and "b" are equal.
