From Proto-Indo-European *loykʷós, cognate with Ancient Greek λοιπός (loipós, “remaining”). Akin to Lithuanian laĩkas (“time”), Latvian laĩks (“time, weather”).
The only certain meaning is “remaining”. There are varying hypotheses regarding the secondary meanings attested in South Slavic dialects:
It is unclear if modern Bulgarian за́лека (záleka, “subtly, with attention to detail”) (possibly also и́злека (ízleka, “barely”), поле́ка (poléka, “steadily, gradually”)), Serbo-Croatian zȁlijek (“for a while, for a bit”) descend from *lěkъ or are recent corruptions of Proto-Slavic *lьgъkъ (“light”).
