- During the First Age in Beleriand, Exilic Quenya lost its distinct accusative case, merging it with the nominative case.
- After the end of the First Age, the Exilic dialect changed word-initial w to v.
- After the end of the Second Age, the dialect changed word-initial ñ to n.
- Also during the Third Age, various words changed whereby sequences of -iV- (where V represents any arbitrary vowel) changed to -iyV-.
It is highly possible that at least some of these changes were adopted in Aman too as Noldor returned by sea over the ages, or died and re-embodied in the Halls of Mandos and rejoined Amanya Noldorin society. However, the Quenya of Aman (including that spoken by the Vanyar and Noldor who remained) is very poorly documented in official sources after the Noldor left Aman in the first place, so any linguistic trends of Amanya Quenya after this point are pure speculation. Indeed, it is difficult to assume the communal living conditions of the Noldor after most of them had returned, including whether they came again to live together in Tirion at all.
