couple translations to check

[mens sparsa]

Would like to check a couple translations:

"Wondering if it will end" - "si desiturum esse mirans"
"He is of a fragile state of mind" - "infirmi mentis affecti est" or "tibi infirmum mentis affectum est"

[adrianus]

"Wondering if it will end" - "si desiturum esse mirans"
"He is of a fragile state of mind" - "infirmi mentis affecti est" or "tibi infirmum mentis affectum est"

1. Vide alibi: http://www.textkit.com/greek-latin-forum/viewtopic.php?f=3&t=38519
"infirmi mentis" Nota: feminini generis est mens nomen
2. "affecti est" falsum est, quod subjectum singulis numeri nominativo casu etsi participium ut scriptum aut pluralis numeri nominativo aut singularis genetivo non nominativo.
Forsit, "infirmâ mente affectus est" seu "Mens infirma eum afficit"

Gratias ago. Non adusque autem scio quod dixisti, praeter exempla et notam, itaque in Anglice relicum transferas? Etiam, rectene sententiam priorem scripsi? Certus non sum quomodo "Could you", "might I", "should they" dicam.

Cheers

Sure. // Libenter.
1. The Latin noun "mens, mentis" is feminine.
2. "Affecti est" is wrong, because the subject [of your English sentence] is nom. sing. while the participle ["affecti"] as written [by you] is either plural nominative or a singular genitive.

"Infirmâ mente affectus est" non "tibi infirmum mentis affectum est", ut opinor, pro "He is of a fragile state of mind" ("He is afflicted by a weak mind")

Ah, nunc sequor. Non itellexi hanc partem "ut scriptum".
Can I use "sequor" in this context? Also would you interpret the last sentence as "I did not understand" or "I have not understood" (because I mean the former)?

Would "tibi infirmus mentis affectus est" or "infirmi mentis affectus est" also make sense, seeing as one meaning of the noun "affectus affectus (4th)" in whitakers words is "state (of body/mind)"? If not, do you know why?

Also, do you have any tips when using the subjunctive, because whenever I use it, I'm never sure whether it will be interpreted as intended (except in certain structures like ut clauses)?

Are there any good ways to ask if something makes sense? I can't find any way to ask if something is ok, or alright, or makes sense.

Cheers

Vestigia genetivo casu usûs cum "afficio" verbo vel "affectus-a-um" adjectivo carent, nisi fallor; porrò feminini generis est "mens" nomen dein non "infirmi mentis".
Maybe I'm wrong but I don't see anything to indicate you would use a genitive instead of an ablative with the verb afficio or adjective affectus (for example, in L&S http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0059%3Aentry%3Dafficio) and Mens mentis is feminine so "infirmae mentis" not "infirmi mentis" in the genitive.

De usu modi subjunctivi, consilium utile non habeo (qui ipse saepe erro) separatim tibi dicere ut in grammaticam bonam inquiras (exempli gratiâ, in hanc: http://www.perseus.tufts.edu/hopper/text?doc=AG+439&fromdoc=Perseus%3Atext%3A1999.04.0001).

On the use of the subjunctive, I personally don't have handy tips (and often make mistakes myself) and can only say study a good grammar (for example, http://www.perseus.tufts.edu/hopper/text?doc=AG+439&fromdoc=Perseus%3Atext%3A1999.04.0001 and the sections that follow on the subjunctive).

Dicam haec (at facundè non loquor)://I would say the following (but I'm not fluent):
Intellegisne? Tenesne quod dico? Capisne quod dicere conor? Intellegisne quod dicere volo? Recténe dico? Satisne intellegis? Estne bonum quod latinè dico/scribo? Mendane [in latinâ scribendâ/dicendâ] facio? Licetne quod scribo/dico?
