Inflection

Ancient Greek λῐ́μνη (límnē) implies a zero grade *limn-, which violates regular PIE sonorant syllabification rules. Taking Ancient Greek λῐ́μνη (límnē) at face value produces the following paradigm:

Athematic, amphikinetic
	singular
nominative	*léymō
genitive	*li‌m‌nés
	singular	dual	plural
nominative	*léymō	*léymonh₁(e)	*léymones
vocative	*léymon	*léymonh₁(e)	*léymones
accusative	*léymonm̥	*léymonh₁(e)	*léymonm̥s
genitive	*li‌m‌nés	*?	*li‌m‌nóHom
ablative	*li‌m‌nés	*?	*li‌m‌n̥mós, *li‌m‌n̥bʰós
dative	*li‌m‌néy	*?	*li‌m‌n̥mós, *li‌m‌n̥bʰós
locative	*limén, *liméni	*?	*li‌m‌n̥sú
instrumental	*li‌m‌néh₁	*?	*li‌m‌n̥mís, *li‌m‌n̥bʰís

Under normal syllabification rules, this word should inflect as:

Athematic, amphikinetic
