To force myself to make up for my usual inefficiency at vocab creation
I'll do all the three languages which I've been active on the last few
years:

Rhodrese (Rhodray/Borgonzay).

: This is a Romlang, so it should mostly be a matter of picking the
    right alternative among those offered by the natlangs! :-)

Euia Twas /ˌɛɥɪa̯ˈtwɑs/

: This is "apriori" (in the artlang sense) but has (Middle) Indo-Aryan
    as a _major_ loanword source. I'll try not to spend too much time in
    MIA-land...

Sohlob

: This is an entire fictional language family. I'll give forms for
    Classical Sohlob and Cidilib plus Proto-Sohlob and for other
    varieties as and when it is possible given my current state of
    knowledge about them.

------------------------------------------------------------------------

**Birthday**

Perhaps not an _every_day word, but it is mine today. :-)

Rhodrese

: _completàn_ /ˌkʊ̃(m)plɪˈtan/

    From _complet (un) an_ 'completes (a) year'. You may note that
    Rhodrese, at least historically and orthographically, preserves the
    _-t_ of the Latin third person singular. (Now how realistic is thát?
    ;-)

    Much the coolest of the Romance natlang alternatives, though I guess
    there are contexts where _anniversair_ are more appropriate.

Euia Twas

: _sawrinyia jaman_ /sɑu̯ˈɾɪŋɪa̯ dʑɑˈmɑn/.

        sawriny -ia jaman
        day -POSS birth

    _jaman_ 'birth'
    : This is of course MIA _jamman_ < Sanskrit _janman_ where _jan-_
        is cognate with English/Latin _gen-_ in _gene, generation,
        gender_. Buddhism buffs may recognise it from _punarjanman_
        'rebirth'.

    _sawriny_ /sau̯ˈɾɪŋ/
    : Almost looks as if a vŗddhi derivative of Skt. _Sūrya_ 'sun
        (god)' lurks somewhere in there, but it is (meant to be) a
        native word. I had a different natlang word festering in my
        brain when I came up with this...

    _-ia_ /ɪa̯/ 'POSS' (a falling diphthong!)
    : This is ET's all-round subordinator morpheme, called the
        "possessive". It cliticizes to the preceding word, which doesn't
        necessarily mean that ET is head-marking.

    FWIW I don't think that the Jan Twas did celebrate birthdays
    traditionally, so this literally means 'the day of which you were
    born'.

Sohlob

: _fresf guruŋ_ /ˈfrɨsfˌguruŋ/

        fresf gur ˗ᵘŋ
        day be born.PRF -GEN

    Proto-Sohlob
    : _*frúsəƀi gúrawəŋa_

    Kijeb
    : _fruswi guruŋa_

    Cidilib
    : _frisp guruŋ_

    Linjeb
    : _gurfrysf_

    Yahab
    : _hrusuy an kuläw_ [ˈr̥usuj ã ˈkuləw]
