Also, I feel like there's a slight difference in meaning between le jaanaa and leke/lekar jaanaa, but I'm having trouble pinpointing it precisely... But maybe that's a topic for another thread
Is it fair to say in the progressive that le jaanaa doesn't work, even for a thing?
- Tomorrow I'm taking my computer to the store to be repaired.
Kal maiN computer theek karne ke liye dukaan (le ja rahaa huN sounds off, no? Or maybe I am overthinking it). Would leke ja rahaa huN be any better in this context?
It would be based on 'ho jaanaa', wouldn't it? main taiyaar ho jaataa huuN, phir chalte haiN is alright but ho jaa rahaa huuN not. The 'jaanaa' modifier indicates more or less that the action is completed (likewise denaa, lenaa, chhoRnaa, baiThnaa etc when made into 'intensive' verbs) so the present continuous tense is incompatible with 'ho jaanaa'.
