Keigo ます after a noun


I found this sentence in an anime.

娘さんたちも悲しみます

The context is that this lady is dying and a guy says to her that her
daughters will be sad.

I understand that he transformed the adjective 悲しい into a noun 悲しみ.

Is the ます a short します ? It would make sense but I didn't know you could do
that.

Thank you




You're right, there is a い adjective called
[悲しい](https://jisho.org/word/%E6%82%B2%E3%81%97%E3%81%84). But the verb
[悲しむ](https://jisho.org/word/%E6%82%B2%E3%81%97%E3%82%80) is what really is
being used here, which is in its ます form. This form is called 丁寧語 (ていねいご) or
what I'd call your standard polite language
