Learning some new English words
In recent times, I have manhandled [1] myself to make my English vocabulary thrive. According to a personal statistics, I've learnt 160 new English words. But I suspect that they became part of my passive vocabulary. Therefore, with the object of transferring them into my active vocabulary, I am forcing/compelling myself to write here using some of these words here. My efforts ascend with a grating. [?? 2] I feel I butcher my unruly brain sometimes, but I think it is nessesary in order to attain a level when it [?? 3] will become my ethos.
PS
The entry looks strange, at the very least. It is just my insufficient imagination in using new words.
[1] Use the "present perfect tense" when an action started in the past and continues until the present moment.
[2] It is hard to understand the sentence "My efforts...." If you paraphrase in English or write the sentence is Russian, I'll try again to help.
[3] I'm not sure what "it" refers to.
