Learn Finnish: Esimies lukee raportin tänään tarkemmin. - The supervisor reads the report more carefully today.

It comes from the adjective tarkka (careful). To make the comparative adverb ("more carefully"), you take the weak stem of the adjective (tarka-), change the final vowel to -e-, and add the comparative adverb suffix -mmin. This gives us tarkemmin.

Why does tarkemmin only have one k, while the base word tarkka has two?

Adding the suffix -mmin closes the final syllable, which triggers consonant gradation. The strong double kk in tarkka must weaken to a single k in tarkemmin.

Why is the object raportin ending in -n instead of being in the partitive case (raporttia)?

The -n ending marks it as a total object (often called the genitive-accusative). This means the supervisor will read the entire report. If the action was incomplete, or if they were only reading some of the report, we would use the partitive form raporttia.

What does the word esimies literally mean?

It literally translates to "fore-man" or "front-man", combining esi- (front, fore-) and mies (man). It is the standard Finnish word used for a boss, supervisor, or manager in a workplace.
