# perjantai
## Finnish
### Etymology

Borrowed from Old Swedish frē(i)adagher, frīadagher, from Proto-West Germanic *Frījā dag.
Since Finnish historically lacks f and initial consonant clusters (such as fr), the word was adapted to fit the language's phonological rules. These changes can be imagined as *freja => *pereja => *perja (On the first step, F turns to P, and an epenthetic vowel appears to avoid the cluster [PR]. Then, on the second step, the unstressed vowel is dropped). For the -antai ending, compare maanantai (“Monday”) and sunnuntai (“Sunday”).

### Pronunciation

* IPA: /ˈperjɑntɑi̯/, [ˈpe̞rjɑ̝n̪t̪ɑ̝i̯]
* Audio:(file)
* Rhymes: -erjɑntɑi
* Hyphenation: per‧jan‧tai

### Noun

day of the week :
| pe | Previous: | torstai |
| pe | Next: | lauantai |
perjantai
* Friday (day of the week; the fifth day of the week in Finland and in the ISO 8601 standard)

#### Usage notes

As with all days of the week in Finnish, the essive case (perjantaina) is usually used when talking about what will happen or happened on a Friday.
