The f component of father was consistently 'lost' amongst many branches of the alphabet:

𓊪 𓏏 𓇯 𓀭 Ptah > दिवि ftvi > ि divi deus sky

This subtle corruption was noticed by ancient grammarians and may have even been the namegiver of a later misinterpreted 'ï' iota ιώτα ≈ ⲓⲟϯ eiōt.
While today iota often refers to the tiny yodh י dot on top of the ι, turning 'ι' into 'i', originally it may have
distinguished aita from Väter.
