Tunnollinen työntekijä tarkistaa työn huolellisesti.

Finnish has no articles, so it does not use separate words for a/an or the.

That means tunnollinen työntekijä can mean a conscientious employee or the conscientious employee, depending on context. The same goes for työn: context tells you whether English should use the work, a piece of work, and so on.

Tunnollinen is an adjective, and here it agrees with työntekijä in nominative singular.

So both words are in the basic subject form:

• tunnollinen työntekijä = a/the conscientious employee

If the noun changed case or number, the adjective would change too:

• tunnollisen työntekijän = of the conscientious employee
• tunnolliset työntekijät = conscientious employees

A useful extra point: adjectives ending in -nen often change to -se- in other forms, so tunnollinen becomes tunnollise- before endings.

Because it is a compound noun, and Finnish uses compounds very often.

• työ = work
• tekijä = doer, maker

So työntekijä literally means something like work-doer, i.e. worker/employee.

In Finnish, compounds are normally written as one word, not two. English often uses separate words where Finnish prefers a compound.

Here tarkistaa is present tense, 3rd person singular:

• (hän) tarkistaa = he/she checks

Because the subject tunnollinen työntekijä is already stated, Finnish does not need a separate pronoun like he or she.

A detail that often surprises learners: with some verbs, the 3rd person singular looks exactly the same as the dictionary form. Tarkistaa is one of those cases.

Finnish does not have a separate progressive form like English is checking.

The present tense can cover both:

• checks
• is checking

Context decides which is more natural. In this sentence, it most naturally sounds like a general/habitual statement: A conscientious employee checks the work carefully.

This is one of the most common Finnish grammar questions.

Here työn is the total object form. In many grammar books, this is connected with the accusative object, but in the singular it usually looks like the genitive ending -n.

So:

• tarkistaa työn = check the whole work/task, viewed as a complete object

If you used työtä instead, that would be the partitive, which often suggests something incomplete, ongoing, indefinite, or partial.

So the sentence uses työn because the work is being checked as a whole.

Huolellisesti is an adverb meaning carefully.

It comes from the adjective:

• huolellinen = careful
• huolellisesti = carefully

A very common Finnish pattern is:

• adjective + -sti → adverb

So huolellisesti tells us how the employee checks the work.

This sentence has a very neutral, standard word order:

• Tunnollinen työntekijä = subject
• tarkistaa = verb
• työn = object
• huolellisesti = adverb

So it follows a straightforward subject–verb–object pattern, with the adverb at the end.

Finnish word order is more flexible than English word order, but changing it usually changes the emphasis or focus. For a learner, this sentence is a very good basic model.

A few helpful points:

• Finnish stress is almost always on the first syllable
• työntekijä is stressed as TYÖNtekijä
• y is pronounced like German ü or French u
• ö is pronounced like German ö or French eu
• yö is a diphthong, pronounced in one syllable

So työn is one syllable, not two. Finnish spelling is very regular, so once you learn the sounds, pronunciation becomes much easier.
