Thank you very much for all your corrections.

Here are a few sentences on Chaucer's the prioress I'd like you to check.

1) In contrast to the nun’s order she showed off and wore ornaments. The nun’s behaviour is contrary to monastic rules (or contrasts the monastic rules, is in contrast with the monastic rules.)
2) She wore fashionable clothes like a graceful cloak (is “like” possible; such fashionable clothes as a graceful cloak?).
3) She was charitable to animals like mice and dogs. She hardly (ever) swore. Does it mean that she swore very little?
4) The Latin inscription “amor vincit omnia” means “love conquers all”.
5) I couldn’t see his face because he was wearing (wore?) a mask which was covering his face.
6) They listen to the witnesses’ descriptions of the criminals and make a picture (a drawing) of the criminals.
Can you say “provide a picture” of the criminals?

1) In contrast to the nun’s order, she showed off and wore ornaments. The nun’s behaviour is contrary to monastic rules.

2) She wore fashionable clothes, such as a graceful cloak. [I wouldn't use "like" in there because you aren't comparing anything. Also ... note the comma.]

3) She was charitable to animals, such as mice and dogs. She hardly ever swore. Does it mean that she swore very little?
[Yes]

4) OK

5) I couldn’t see his face because he was wearing a mask which covered his face. ["wore" is OK, too]

6) They listen to the witnesses’ descriptions and make a drawing of the criminals.

Can you say “provide a picture” of the criminals? [I wouldn't; "make a drawing" is just fine.]
