On: English as She Is Spoke

[ma2rten]

DeepL (which is sometimes better than Google) returns almost the same translation:

This lake looks pretty fishy to me. Let's go fishing for fun.

Maybe the language that the book uses is dated making those machine translation systems trip up?

[frozenlettuce → ma2rten]

"piscoso" is a very specific term (if I google that I get just dictionary entries, almost no actual use). Replacing it with "cheio de peixe" (full of fish) would make the translation much easier
