I want to make a coat of arms for my father in law, and we always refer to him doing anything with the phrase - "that'll do". Is there a Latin phrase that this translates to? Google translate has suggested 'hoc faciam' but reverse translating it changes the meaning.
Correct me if I'm wrong, but that'll do is slang/an idiom for that's enough (pretty much in the speaker's subjective point of view.)
On one hand, we know little about slang Latin although vulgar and medieval Latin could somehow do the job. I'm no expert in any of those, although what I have is a quote from the Vulgate (Latin translation of the Bible from the IV century,) which is late Latin. At least it is not Classical, in which case you would have what is arguably the opposite of slang.
On the other hand, that'll do in the sense of that's enough may have more than one reading, judging from what I read here: from a soft that's ok, thank you to a hard stop it!. In the later case I would recommend Joonas' satis.
But what came to my mind is:
Sufficit is a conjugated form of the verb sufficio, which among its meanings includes: to be sufficient, to suffice, avail for, meet the need of, satisfy, and is attested in this sense in the Vulgate e.g. in 2 Cor 12, 9:
sufficit tibi gratia mea // My grace is enough for you,
It is in 3rd person singular, meaning that the it (as in it's enough) is (arguably) explicit. The cite above also implies that you can use the personal pronoun in dative to remark for whom is something enough, hence sufficit mihi-it's enough for me.
Now, using the first person in a real coat of arms would be daring, but given it's a satirical one, it's more of a matter of choice.
I'm not aware of a perfect match, but here are two alternatives to express that the situation is good enough:
- Satis. — "Enough." (See this dictionary entry for satis.)
- Satisfacit. — "[It] suffices." (See this dictionary entry for the verb satisfacio.)
A similar effect to the first alternative is reached with the adverb sufficienter, but it's rarer. However, the tone might be better, as satis can be read as "too much" or "stop", whereas sufficienter is more neutral.
