Learn Turkish: Bu turda rakibi yenecek miyiz? - Will we beat the opponent in this round?

In the Turkish future tense, the personal suffix (here, -iz for 'we') attaches to the question particle mi, not the main verb. So we say yenecek miyiz? instead of 'yeneceğiz mi?'. We also need the buffer letter y between the two vowels.

Why is it rakibi and not rakipi?

The root word is rakip (opponent). When we add the accusative case ending -i because we are talking about a specific opponent, the hard consonant p changes to a soft b. This consonant mutation makes the word easier to pronounce.

Why does rakip need the accusative case ending here?

In Turkish, specific direct objects take the accusative case ending. Because we are asking about beating a known, specific opponent in this match, we use rakibi. If we were asking generally about beating any opponent, it would just be rakip yenecek miyiz?.

Does tur always mean 'round' like in a game?

Tur can mean 'round' in a tournament, but it is also the word for a 'tour' (like a sightseeing tour) or a 'lap' (in a race). Here, the context of beating an opponent makes 'round' the best fit.
