Anyone knows what the English word for this one: /tɒrp/ is? Appreciate your response.?

There isn’t one in standard English.

In UK English, “ɒ” is the vowel sound in “hot”.

There is an obscure word “torp” (a kind of Scandinavian house http://en.wikipedia.org/wiki/Torp ) but the IPA spelling would be /tɔːp/ (or /tɔːrp/ for rhotic speakers). Nor is it “tarp” (abbreviation for tarpaulin): that’d be /tɑːp/ (or /tɑːrp/ for rhotic speakers).

It might conceivably be a dialect pronunciation of “top” (Boston, maybe?).
