it seems google translates some words but not others

our fellow mylotter, birju1988, posted about his favorite lunch, "Bhindi Sabji". the other items on his plate were: "banana, dal and roti." from the picture he shared, and using context clues, and some words i'm already familiar with, i can guess which is which, more or less. however, out of curiosity, i still right-clicked on each word to confirm if i'm correct. i know roti is bread and when i searched roti, the result showed roti from wikipedia. when i searched dal, the result also showed dal from wikipedia. he did write 'ladies finger' after bhindi, which i know is another name for okra, so i was expecting when i right-clicked on bhindi, the result would also be for bhindi. but the result was okra from wikipedia. it was the same with 'sabji'. the result showed vegetable from wikipedia. do you also get curious about what you read here and look them up? and if you don't mind, since mylot is an international site, i've always wondered: what language does your computer use? ours has always been english (of course, we can also search in filipino and other dialects)
