'Hoc Vince' is the Latin for 'By this conquer!'
The meaning of hoc is "this" in place of a noun (with hoc being the pronoun). An example of hoc being used in a phrase is ad hoc which means "for this", such as an ad hoc committee or a committee created for a specific purpose or outcome.
It means this; or hither.
The translation of Pointe du Hoc is Hook Point.
Ad hoc means "formed, arranged or done for a particular purpose only. From Latin, literally "for this"
"Hoc eritis" is a Latin phrase that translates to "This you will be." In Latin, "hoc" means "this" and "eritis" is the future tense form of the verb "to be." Therefore, the phrase implies a future state of being or existence.
It means 'This Signal'.
Ad hoc.
Literally "What does this want for itself?", Quid hoc sibi vult is a Latin idiom that means "What does this mean?"Quoted with quod rather than quid, it means "[Which is] what this means".
"In this year of our Lord"
Ad hoc is not generally translated into English, it's left untranslated (pronounced "add hock"). If you're looking for a translation, it's literally "to this", and is used to mean "formed for a specific purpose only" ("an ad hoc committee") or sometimes "spontaneous; improvised" ("an ad hoc piano recital").
The statement 'Meus adjutor vince in hoc dominus agla' contains errors. The word 'adjutor' needs to be written 'adiutor'. The word 'meus' preferably follows, instead of going before. The word 'hoc' needs to be written 'hac'. The word 'dominus' needs to be written 'domu'. And the word 'agla' needs to be written 'Aglaia'. The meaning of the corrected phrase, 'Adiutor meus vince in hac domu Aglaiae', is My helper, conquer in this house of Aglaia*. In the word-by-word translation, the noun 'adiutor' means 'deputy, helper'. The possessive adjective 'meus' means 'my'. The verb 'vince' means 'conquer', in the imperative active. The preposition 'in' means 'among, in, on, within'. The demonstrative pronoun 'hac' means 'this'. And the noun 'domu' means 'house'. *Aglaia is the name of one of the Three Graces of charm and beauty.
"Du hoc" is not a French word. It may be a misspelling or a term in another language. Can you provide more context or specify the language you are referring to?
