Questions & Answers about Я так вымотался, что чувствую полное изнеможение.
Where does the verb вымотался come from, and is it a formal or informal word?
It comes from the verb мотать, which means to wind or reel (like thread). By adding the prefix вы- (meaning outwards or to completion) and the reflexive suffix -ся (to oneself), the literal image is winding oneself out or unraveling until there is nothing left. It is a highly expressive, colloquial word, much more colorful than the standard устал.
How does изнеможение compare to a more basic word like усталость?
Изнеможение is significantly stronger. While усталость just means tiredness, изнеможение means total exhaustion or prostration. You can see the root мочь (power or ability) inside it—it literally describes a state where you have no power left.
Can I use такой instead of так in the phrase так вымотался, что...?
No, because вымотался is a verb. You must use the adverb так to modify verbs or other adverbs (I got so worn out). You would only use такой if you were modifying a noun, for example, такая усталость, что... (such tiredness that...).
Why do the tenses switch from past perfective in вымотался to present imperfective in чувствую?
