Those words are not listed because Bethesda has not produced any draconic material where they appear. The closest available equivalents are sil 'soul' and sos 'blood'.

What text or environment do you need them for? Given the context, someone might be able to craft a translation without needing the exact meanings.

The solution here will be to craft a descriptive compound from existing vocabulary. The manner of that is fairly free; I suggest combining one of these attributes

sos- 'blood'
laas- 'life'
kosil- 'inner'

with one of these nouns

-nos 'striking'
-tu 'hammer'
-yoriik 'march'
