Via other European languages, ultimately borrowed from Latin sexus (“sex, gender”).

• IPA^(key): [sɛks]

sekss m (1st declension)

1. sex, gender (the two groups in which most living beings can be divided, according to their role in the reproductive process)

   sieviešu sekss ― the female sex

2. (usually singular) sex (sexual intercourse, sexual activity)

   seksa fiziskās izpausmes ― physical manifestations of sex

   seksa horoskops ― sex horoscope

   cik bieži latviešu sievietēm ir sekss? ― how often do Latvian women have sex?

The use of sekss to mean "biological group" apparently is (or is becoming) dated; dzimums is more often found in this sense.

• (of "sexual intercourse"): dzimumakts, dzimumattiecības

• seksīgs, seksīgums
• sekssimbols
