I am trying to learn how to say 'to talk/write/read about smth' in Japanese, since corrections natives make to my sentences seems not to be very consistent. For example, let us consider a phrase 'I talked/read/wrote about pencils'. Particles I want to use are を and で. With 'talked', it seems that 鉛筆を話した is just fine, because here topic kinda fits into my understanding of 'direct object', but 鉛筆を書いた would mean 'i drawed a pencil', while 鉛筆で書いた would mean 'i wrote with a pencil'. What would one use instead? I tried to search Dictionary of Basic Japanese Grammar for で, but with no success.
について is what you are looking for.
It translates as 'concerning', 'regarding', 'about' etc. Your sentences would look something like:
