Questions & Answers about Yüzeyde yürümek bizim için çok zor olurdu.
Why is yürümek used here to mean 'walking' instead of just 'to walk'?
In Turkish, the infinitive form ending in -mak or -mek naturally acts as a verbal noun. This means yürümek can translate directly to the act of 'walking'. Using the infinitive is the standard way to make a verb the subject of a sentence like this.
Why does the sentence use bizim için instead of just biz için?
The word için (for) is a postposition. When used with most personal pronouns (I, you, we, etc.), Turkish requires the pronoun to be in the genitive (possessive) case. That is why you must say bizim için (literally 'for our'), just like you say benim için (for me).
How does olurdu translate to 'would be'?
The word olurdu combines the verb stem ol- (to be/become), the aorist suffix -ur (which usually shows a general fact or habit), and the past tense suffix -du. In Turkish grammar, combining the aorist and the past tense creates a hypothetical or unreal condition. This combination is exactly how you express 'would' in English.
How do we know yüzeyde means 'on' the surface rather than 'in' or 'at'?
