Reconstruction:Proto-Indo-European/dʰugh₂tḗr

Etymology
Perhaps from, originally meaning "the (potential) suckler, the one that draws milk" (compare 🇨🇬 / ), , the agentive nominal suffix common to other r-stem kinship terms.

Noun

 * 1)  daughter

Reconstruction notes
There are two PIE reconstructions that can be obtained using the comparative method: The latter form is secondary, occurring due to the deletion of the medial laryngeal in the sequence CHCC in the oblique stem, which was paradigmatically leveled in the daughters. E.g. genitive singular *dʰugh₂tr̥és > *dʰuktr̥és. The CHCC > CCC change was a synchronic PIE phonological rule, now called Schmidt–Hackstein's law.
 * *dʰugh₂ter- on the basis of: PIIr. *dʰugHtar- (Sanskrit duhitár-, PIr. *dʰugʰtar- > *dʰugdʰar- > *dugdar- > Gathic Avestan dugədar-), Ancient Greek thugátēr-, Tocharian A ckācer, Tocharian B tkācer
 * *dʰukter- on the basis of: Iranian *duxθrī (> Old Persian *duhçī) and *duxtar- (> New Persian duxtar) due to the absence of, possibly Gaulish duxtir, Gothic dáuhtar, Oscan fu-utreí (dative singular), Armenian dustr, Hieroglyphic Luwian t(u)watra/i-, Lycian kbatra-, Slavic *dъkti > *dъťi, Lithuanian duktė̃

According to Kloekhorst, hieroglyphic Luwian tu(w)atra/i- and Lycian kbatra- reflect Proto-Luwic *duetr-, further reflecting Proto-Anatolian *duegtr- < PIE full-grade stem *dʰwegh₂ter-. The original inflection was thus hysterodynamic bandi-type as described by Beekes (1995: 175): *CéC-R, *CC-éR-m, *CC-R-ós: After the split of Anatolian branch from Proto-Indo-European, the other Indo-European languages underwent a common innovation, replacing the nominative stem *dʰwégh₂tr̥ by the accusative stem in the zero-grade *dʰúgh₂tēr which however retained the original accentuation and which further underlies the attested Greek forms *θύγατηρ (Homeric ) > (θυγατέρα, θυγατρός). In the other Indo-European languages the accentuation of the accusative was later on transferred to the nominative form, yielding the oxytonic paradigm listed in the declension table, as retained in Sanskrit (duhitā́, duhitáram, duhitúḥ) and Lithuanian (duktė̃, dùkterį, dukterès).
 * Nominative singular: *dʰwégh₂-tr̥
 * Accusative singular: *dʰugh₂-tér-m̥
 * Genitive singular: *dʰugh₂-tr-ós
