As I understand it, infinitive is a form of a verb with no reference to a particular tense, person, or subject. In English , an infinitive is usually preceded by the word "to", as is the case here in 'to pronounce with velar articulation."
Like I said in my first posting, the word I have is 'velarize', what I don't know is, and what I would like to know, do I write the addidtional letter as an "s" or an "d" to make it a 9 letter word ,which is what they are asking for. In short is it "velarizes" or "velarized"?
(Roberta although I show an 8 letter word, I did include the letters 's' and 'd' to use either to make it a nine letter word. I trust you can follow me.
