Previously, I was asking help for some right words to describe a conversation that swaps between On and Off states. In the question, I wrote this,
My spoken English is not very good, my Vocabulary is weak either.
And some time later, I received some suggestion to improve my question, and the word, Either has been replaced by Too.
I came across some English web sites where the authors said that "either" is used in negative sentences. My understanding is that "weak" and "poor" are words that will make negative meaning in sentences.
