in English 'to go' is differing from 'to walk' is there such a difference in Russian, and does it apply here? In English the sentence could be both: "Are you old enough already for going to school?" but also "It is early in the morning, and you are going to school already!"
Yes we really pronounce these three consonants without any problems. To be honest, I never thought about how difficult it is ) It's hard to me as a person who learned English to get used to pronouncing sounds in a row ending in "th" and "s". It's not possible to quickly pronounce these sounds in a row, they merge into one ))
