Hi Mahsun, Good question. An 'institute' is a group or society that tries to study something. Sometimes the building that they work in is called an institute as well. An 'institution' can be an institute, but an institution can also be a cultural behaviour or widely-known phenomenon. In Canada, we love Tim Horton's coffee, and so we say Tim Horton's is a national institution. We can also say that going to Tim Horton's and drinking their coffee is a national institution. In this case, however, it is the behaviour that makes Tim Horton's an institution - because it does not do or study anything on its own except sell coffee, it is not an institute. Keep in mind that both of these words are available as verbs as well - we are only talking about nouns here. I hope that helps!

They are different. Any school and some traditions are institutions. The US Supreme Court is an institution. A university is an institution of higher learning. Languages can be studied a language institute. Some institutes are devoted to other subjects.

institute = next level after "school" institution = establishment
