huippuosaaja (compound noun) –
In today’s example, on signs for Tehys, a Health and Social Care Professional union, we see the compound word ”huippuosaaja!” which means ”top expert.” (It appears here with a dash because the word is shown on two lines.)
Huippu is a noun meaning ”top,” peak” or ”summit.”
Osaaja is a noun meaning ”expert.”
The whole phrase, tältä näyttää huippuosaaja means literally ”From this appears the top expert,” or more figuratively, ”This looks like a top expert” referring to the woman looking at herself in the mirror and picturing herself as a health professional.
Tältä here is the ablative form of tämä, meaning this. In the ablative it means ”from this,” ”off this” or ”of this.”
Näyttää here is a verb appearing simply in the 3rd person present, meaning ”present” or ”show.”
The rest of the text of the sign touts the great training health professionals get, etc.
