DEF-F.C song of-DEF.M fate 3S.F.NOM may.3S change-INF of melody | but 3S.F.NOM 3S.REFL stop-3S never
The song of fate may change its melody, but it never stops.

Structurally similar to English in this case. The big differences are that peu "may" and many other auxiliaries are obligatorily preceded by a subject pronoun, even when there is an explicit nominal subject. Additionally, like in French and other Romance languages, when talking of "changing" something, it isn't common to use possessive pronouns; the preposition de is preferred.

Yélian

Æʻèlden o'iadul o'tanek diʻareyvut, cut æ'iadul rocidiyszonet.
[əˈʔɛldən ɔ̈ˈɪ̯aːdʉl ɔ̈ˈtaːnə‿dɨʔɐˈɾeʃvʉt, kʉt əˈɪ̯aːdʉl ɾɔ̈ˌkida̯iːscoːnət]
DEF.CONC=melody DEF.GEN=song DEF.GEN=destiny COND-change-COND.INV.3SG.INAN, but DEF.CONC=song FUT-never-stop-3SG
The melody of the song of destiny may be altered, but the song never stops.

This sentence requires a rather clunky structure in Yélian, which lacks possessive pronouns for inanimate 3sg subjects. Therefore, the inverse conditional conjugation of the verb needs to be used with "melody" as the subject. If this sentence was used in an everyday communication instead of a written text, native Yélians would propably word it differently:

Vut tyaʻareyet æ'èlden o'iadul o'tanek, cut dé rocidiyszonet.
3SG.INDEF POT-change-3SG DEF.CONC=melody DEF.GEN=song DEF.GEN=destiny, but 3SG.REF FUT-never-stop-3SG
One can change the melody of the song of destiny, but (it) never stops.

Note that here, an indefinite construction is used that requires neither inverse nor conditional. Furthermore, the noun is not repeated in the second subordinate clause; instead, the generic pronoun "dé" is used. While strongly discouraged by descriptive grammarists, it's quite prevalent in colloquial Yélian and always refers to one noun in the last sentence that was not the subject; it's ambiguous if the "song" or "destiny" is referenced, but nevertheless the meaning is clear.
