Ooof. One more:

nombre d'or

I'm not sure why you are concerned with translating. You say you understand them and that is probably enough. The more I get immersed in French the less I concern myself with translations. I understand them; they understand moi. The reality is--exact word for word translations don't exist for many phrases. Language and communication is really so much more than that.

Nouer une nouvelle tresse:

To tie a new braid

I don't have the context but that is probably an image for "making new ties"

***

Conduite tactique:

Tactical move/ tactical behaviour (depending on the context again)

***

Coup de théâtre:

An unexpected change (of a situation)

***

Voyage d'étude:

a study trip/ a field study (again it's a matter of context)

****

désinence:

in ethymology, the ending of a term following the radical

****

Face d'ombre:

a shadow face (that's probably a poetical image)


***

les traits bavent:

the lines gush

it sounds like the saying of an art critic speaking about one's painting

****
toujours plus chargées de sortilèges que ce qui s'en entend:

Always more spell-filled than what we ear about

(go figure... maybe with the context you'll understand. I don't)


Hope this helps
