Questions & Answers about Я всегда кладу студбилет в кошелёк, чтобы не забыть его дома.

Why is it кладу, not ложу?

In standard Russian, the normal verb here is класть = to put, to place. Its 1st person singular present form is кладу: я кладу = I put.

Many learners expect ложу from ложить, but ложить is generally considered nonstandard in modern literary Russian. So:

• я кладу = correct standard Russian
• я ложу = usually treated as incorrect/nonstandard

A very common pair is:

• класть → imperfective: to put, to be putting
• положить → perfective: to put, to place once / successfully

So Я всегда кладу... means I always put... as a habitual action.

Why is кладу in the present tense if the sentence talks about a general habit?

In Russian, the present tense is commonly used for habitual actions, just like in English:

• Я всегда кладу... = I always put...

It does not mean only right now. It can also mean as a regular habit. The word всегда (always) makes the habitual meaning very clear.
