Learn Hardcore Croatian: On također govori engleski.

Također govori engleski. (Also speaks English.)
Govori i engleski. (Speaks English as well.) Include On if you want clarity or emphasis on the person: On također govori engleski.

Where can I put također in the sentence?

Most natural positions:

Neutral/additive: On također govori engleski.
Sentence-initial (linking with what came before): Također govori engleski.
To add the object specifically: On govori i engleski. (The particle i sits before what’s being added.)
To add the subject specifically: I on govori engleski. (He, too, speaks English.) Less natural or stylistically marked:
On govori engleski također. (Possible, somewhat formal/written.) Avoid:
On govori također engleski. (sounds awkward)
On također engleski govori. (heavy emphasis, odd in everyday speech)

What’s the difference between također, i, isto, and takođe?

također = also/as well; neutral, standard in Croatian, common in writing but fine in speech.
i = and; also works as a focus particle meaning also/too when placed before the added element: On govori i engleski.
isto = same; colloquially also means also/too, especially at the end or alone: Ja isto. It’s informal.
takođe = Serbian form; not standard in Croatian (use također in Croatian).

Why is engleski lowercased?

In Croatian, names of languages and nationalities are written in lowercase: engleski, hrvatski, njemački. Capitalize only at the beginning of a sentence.

Why is there no na (as in na engleskom) here?

govoriti engleski = speak English (ability/habit).
govoriti na engleskom = speak in English (the current medium). Examples:
On govori engleski i njemački. (He speaks English and German.)
Sada govori na engleskom. (He is speaking in English now.)

Is govoriti the right verb for speaking a language? What about pričati?

Use govoriti for languages: On govori engleski. pričati means to chat/tell a story: pričati priču, pričati s prijateljem. Saying On priča engleski is non‑standard in Croatian (though heard regionally); stick to govoriti.

How do I ask Does he also speak English?

Use the clitic li after the first word:

Govori li i on engleski? (Does he, too, speak English?)
Govori li i engleski? (Does he speak English as well?)
Govori li on također engleski? (acceptable, a bit heavier) Note: Da li is common regionally but not preferred in standard Croatian; Govori li …? is the standard pattern.

How do I say He doesn’t speak English either?

The most natural negative additive is with ni:

Ni on ne govori engleski. You can say On također ne govori engleski to mean He also doesn’t speak English (in addition to someone else), but for either/too in negatives, ni … ne is the go‑to.
