That whole maglor adopting elrond and elros sequence is relatively short, and leaves a great chasm into what actually happened. For instance, did elrond and elros actually know as children what happened to earendil and elwing?Social cognitive learning theory did maglor even know? It could be assumed that they had died, couldn't it? And who would be to blame for that but the sons of feanor? Seems odd that great love could spring from this adoption unless there was at least an inkling about what happened.Social cognitive learning theory

I think almost everyone would have thought them both dead. Earendil was trying to sail to valinor, an endeavour which had sunk almost every ship that attempted it; when he didn't come back, the natural assumption would be that he was just the latest casualty.Social cognitive learning theory elwing was last seen leaping off a cliff into the sea; only a crazy person would believe she'd been magically transformed into a bird on the way down.Social cognitive learning theory

That great love did spring from maglor's raising of the pair is seen through those very names: the timelines suggest the twins were six at the third kinslaying, easily old enough to remember their own names!Social cognitive learning theory I'd conjecture that they refused to give their names to maglor when he found them - he was, after all, the person who'd just destroyed their home, even if they didn't know about their mother yet - and so he coined two nicknames for them.Social cognitive learning theory the fact that those nicknames stuck, and were still in use over six thousand years later, tells you how close they must have been.

Chosen-name in which point, maybe, the noldor differed from the other eldar.Social cognitive learning theory it is said here that the elf-child had the right to name himself or herslf. The ceremony of name-choosing could not take place before the child was deemed ready and capable of lámatyáve, as the noldor called it: that is, of individal pleasure in the sounds and forms of words.Social cognitive learning theory in elder times the chosen-name or second name was usually freshly devised. In later ages, when there was a great abundance of names already in existence, '...It was more often selected from names that were known.Social cognitive learning theory but even so some modification of the old name might be made.' JRRT

This wording does not seem to imply (in my opinion) that it was absolutely necessary that some modification must be made to the chosen-name, but that it "might" be made.Social cognitive learning theory in any case the 'true-names' are here said to be the father-name and chosen-name, and the chosen-names were said to be regarded by the noldor as part of their personal property.Social cognitive learning theory new chosen names could be added.

Here we have the mother-name, a name of insight or of foresight. A mother-name was given in the hour of birth or on some other occasion of moment, indicating some dominant feature of the elf-child's nature as perceived by her, or some foresight of its special fate.Social cognitive learning theory when solemnly given a mother-name could also be regarded as a true name and was sometimes placed immediately after the father-name. Mother-names of insight in general use sometimes replaced the father-name and chosen-name, however the father-name and the chosen-name (among those that had the custom of essecilme that is) remained ever the true or primary name, and a necessary part of any full title.Social cognitive learning theory

Epesse 'after-name' a nickname not necessarily given by kin and mostly given as a title of admiration or honour. Later some among the exiles gave themselves names, as disguises or in reference to their own deeds and personal history: such names were called cilmessi 'self-names'.Social cognitive learning theory the true names remained the father and mother-names it seems, according to this account.
