Lukekaa vakuutusehdot huolellisesti.

Lukekaa is the imperative form of lukea for second person plural. In plain English, it is the form used for telling you all to do something.

So:

• lukea = the dictionary form, to read
• lukekaa = read! when speaking to more than one person

The ending -kaa / -kää is the typical plural imperative ending in Finnish.

Finnish usually does not need a subject pronoun when the verb ending already shows who is being addressed.

In this sentence, lukekaa already tells you that the command is aimed at you plural (or formal you), so te is normally left out.

You could say Te lukekaa..., but that would usually sound marked or emphatic rather than neutral.

Yes, it can be used to one person in formal/polite address, because Finnish uses te as a polite form in some contexts.

So lukekaa can mean:

• read! to several people
• read! to one person formally

That said, in modern everyday Finnish, very formal direct imperatives are not always the most common polite style. People often soften commands in other ways.

You would use lue:

Lue vakuutusehdot huolellisesti.

So the contrast is:

• lue = read! to one person informally
• lukekaa = read! to several people, or to one person formally

Because Finnish very often forms compound nouns as one word.

Vakuutusehdot is built from:

• vakuutus = insurance
• ehdot = terms / conditions

Together they form one compound noun: vakuutusehdot = insurance terms/conditions.

This is very normal in Finnish. English often writes these as separate words, but Finnish commonly joins them into one.

The dictionary form is vakuutusehto.

Here is the pattern:

• vakuutusehto = an insurance term / condition
• vakuutusehdot = insurance terms / conditions

So the sentence uses the plural form.

Vakuutusehdot is in the nominative plural form, and here it functions as the object of the verb.

A useful learner-friendly way to think about it is this:

• vakuutusehdot refers to the whole set of terms/conditions
• the sentence is telling someone to read them completely, not just some of them

Finnish objects can appear in different forms depending on meaning and grammar. In this sentence, vakuutusehdot is the normal form for a plural total object.

Vakuutusehtoja is the partitive plural, and it would give a different nuance.

Compare:

• vakuutusehdot = the insurance terms, understood as the whole set
• vakuutusehtoja = some insurance terms, or terms in a less complete/less bounded sense

So Lukekaa vakuutusehdot huolellisesti suggests read the full terms carefully.

If you used vakuutusehtoja, it could sound more like read some insurance terms or be reading insurance terms without the same sense of completeness.

Huolellisesti is an adverb. It tells you how the action is done.

It comes from the adjective huolellinen, which means careful.

So:

• huolellinen = careful
• huolellisesti = carefully

The ending -sti is a very common way to form adverbs in Finnish, somewhat similar to English -ly.

This is a very natural, neutral Finnish word order for a command:

1. Lukekaa — the command verb comes first
2. vakuutusehdot — the object
3. huolellisesti — the adverb describing how to do it

So the structure is basically:

Verb + object + adverb

Finnish word order is flexible, but this version sounds straightforward and normal. Changing the order can shift emphasis. For example, putting huolellisesti earlier would emphasize carefully more strongly.

It comes from the verb lukea plus the plural imperative ending -kaa.

Very roughly:

• dictionary form: lukea
• imperative stem: luke-
• plural command ending: -kaa
• result: lukekaa

The exact historical grammar behind verb formation is more complicated, but for a learner it is enough to recognize -kaa / -kää as the usual ending for a command directed at you plural.

It can be either, depending on context.

In practice, Lukekaa vakuutusehdot huolellisesti often sounds like a formal instruction, especially in writing, for example:

• in a contract
• on a website
• in official customer information

So although it is grammatically an imperative, in this kind of context it often feels more like Please read the insurance terms carefully than like someone sharply ordering you around.
