This has led to the more recent idea that PIE had a number of synchronic "laryngeal deletion" rules, where syllabic laryngeals in particular contexts were deleted even in the protolanguage. In the case of *, for example, it appears that PIE had an alternation between a "strong" stem * and a "weak" stem *, where a deletion rule eliminated the laryngeal in the latter context but not the former one. Forms in daughter languages with the laryngeal (Ancient Greek "thugátēr", Sanskrit "duhitṛ") or without the laryngeal (Gothic "dauhtar", Lithuanian "duktė̃") are due to analogical generalization of one or the other protoforms.
