U-stem nouns constituted a relic class in Old English, and tended to be transferred to the a-stem (if masculine) or ō-stem (if feminine) declension classes. The noun lagu~lago is attested with u-stem endings only in the nominative and accusative singular.
Borrowed (ca. 1000 C.E.) from Old Norse lǫg (“the things that are laid down, the laws”), originally a neuter plural but reanalysed as a feminine singular when it was borrowed into 古期英語. From the singular Proto-Germanic *lagą (“something laid”), from Proto-Indo-European *legʰ-, the root of English lie, lay.
The Old Icelandic word means "something laid down or fixed", both in the literal sense of "layer, stratum" and in the figurative "agreed share", "fixed price", "partnership", etc. The plural had the collective sense of "[body of] law". The native 古期英語 word replaced by the Old Norse loan was ǣ.
