Then use the Braemoor French caving glossary to translate the caving specific words in to the appropriate English ones.I cannot help regarding books.
However I have had reasonable success taking a picture of a page in foreign book, then searching the picture with “Google Lense” to extract the text and then use Google translate.
It is a lot simpler than it sounds, trust me 😂
Google Lens will now do the translation itself, you don't have to copy it into Translate. It's quite startling to be in a country where you don't read the language, photograph a sign and immediately see the English words overlaid on it!searching the picture with “Google Lense” to extract the text and then use Google translate
