Questions & Answers about Я советую это как аналитик.
Why is аналитик in the Nominative case here?
When как means "in the capacity of" or "as," the noun that follows it must agree with the case of the noun or pronoun it refers to. Here, the analyst is Я (I), which is the subject and therefore in the Nominative case. Because they match, аналитик is also in the Nominative.
How would this sentence change if I wanted to use в качестве instead of как?
You would say Я советую это в качестве аналитика. Unlike как, which copies the case of the word it refers to, the phrase в качестве (in the capacity of) always requires the Genitive case. The meaning remains exactly the same, though в качестве sounds a bit more formal.
Why does the verb советую look so different from its infinitive, советовать?
This is a very common verb pattern to remember: verbs ending in -овать or -евать drop the -ова- or -ева- and replace it with -у- or -ю- when conjugated in the present tense. That is why совет-ова-ть turns into я совет-у-ю.
Is the word это (this) in the Nominative or Accusative case in this sentence?
