Taistelemme yhdessä.

Taistelemme is the verb, and it is in the present tense, first person plural.

So it means:

• we fight
• we are fighting

In Finnish, one verb form can already include the subject, so taistelemme by itself already tells you that the subject is we.

The ending -mme is the personal ending for we.

So:

• taistelen = I fight
• taistelet = you fight
• taistelemme = we fight

This is why Finnish often does not need a separate subject pronoun like me for we.

Taistella is the basic dictionary form, meaning to fight.

It is a type 3 verb. With this verb type, the ending changes when you conjugate it:

• taistella → stem taistele-
• taistele- + mme → taistelemme

So the form is built like this:

taistella → taistele- → taistelemme

Because Finnish usually does not need the subject pronoun when the verb ending already shows who is doing the action.

So both of these are possible:

• Taistelemme yhdessä.
• Me taistelemme yhdessä.

The version without me is completely normal. Adding me can give extra emphasis or contrast, like we in particular.

Yhdessä is an adverb, and here it means together.

It describes how the action happens:

• taistelemme = we fight
• yhdessä = together

So yhdessä does not change according to person the way the verb does.

Yes, depending on context.

Finnish does not have a separate future tense in the same way English does. The present tense is often used for both present and future meaning.

So Taistelemme yhdessä can mean:

• we fight together
• we are fighting together
• we will fight together

The surrounding context tells you which one is meant.

Yes. Finnish word order is fairly flexible, and changing the order usually changes the emphasis, not the basic meaning.

For example:

• Taistelemme yhdessä. = neutral, natural
• Me taistelemme yhdessä. = emphasizes we
• Yhdessä taistelemme. = emphasizes together

So the original sentence is natural, but other orders are also possible.

A simple guide is:

TAIS-te-lem-me YH-des-sä

A few useful points:

• The stress is on the first syllable of each word.
• ai in tais- is pronounced like the vowel sound in tie.
• The y in yhdessä is not an English y sound. It is more like German ü or French u.
• Double consonants are pronounced longer, so mm and ss are both held a bit longer.

In Finnish, double consonants are real and important. They are pronounced longer than single consonants.

So:

• mm in taistelemme
• ss in yhdessä

are not just spelling details. Consonant length can change meaning in Finnish, so learners should try to notice and pronounce double letters clearly.

That would usually be:

Taistellaan yhdessä.

This is different from Taistelemme yhdessä.

• Taistelemme yhdessä = we fight / we are fighting together
• Taistellaan yhdessä = let’s fight together

So the original sentence is a statement, not a suggestion or command.
