The word "pregnants" is not a correct spelling in English. The correct spelling is "pregnant" with an [ˈprɛɡ.nənt] pronunciation. The pronunciation of "pregnants" would be [prɪˈɡænts], indicating the addition of an "s" after "pregnant." However, adding an "s" to "pregnant" creates a plural which is not used, as "pregnant" is used only as a singular noun and adjective. Therefore, it is important to learn and use correct spellings in writing and speaking English.
There seems to be a bit of confusion regarding the term pregnants, as it is not a recognized word in English. It is likely a misspelling or error. If you intended to reference the term pregnant, then its etymology can be traced back to the Latin word praegnans, which means with child or full of offspring.
