Is it permissible to learn dikduk of Biblical Hebrew on tish’ah b’av or is it considered learning Torah?
If a grammar or book one is using to learn dikduk quotes pesukim or phrases from תנ״ך to show examples of the grammar rules being discussed is that considered learning Torah and asur on tish’ah b’av? Since the examples are being used to support the points of grammar and not for the sake of learning Torah per se would this be permissible and not be considered Torah study?
