Datcha is a word originally arising from a corruption of the
words "that's a". It is a contraction of "that's a" but can be used for other purposes. Other related
words are ditcha ("this is a"), dotcha ("that was a"), and detcha ("this was a"). Also used in place of "that" or "that'
s" (rarely). All forms are interchangable with "an" or "a" (as in "Datcha airplane")
