Question: Possible Duplicate: What is the correct way to pluralize an acronym? What's the plural form of "SMS" (if X), like: I'm concerned, I sent him over a million X but got no response. I usually use text message to get rid of that situation. 
Answer: The common way to pluralize acronyms is to add a lowercase S, so it would be SMSs. But SMS (short message service) is not usually used like that. SMS is the service you use to send text messages. SMS can also be used to talk about a feature-set ("It's got unlimited SMS."), or a technology ("This tablet supports SMS."). Both text (sometimes abbreviated txt) and text message are used. I'm concerned. I sent him over a million texts, but got no response. or I'm concerned. I sent him over a million text messages, but got no response. Google Ngram seems to support this:.

Ex Output:
yes


Ex Input:
Question: I'm describing what an opiate addict looks like before recovery. Instead of saying "he looked like a vampire," I'd like to say something like "he looked [vampiric]." I actually just found out vampiric was a word, but I want something that sounds better (more colloquial/natural, I suppose) and covers a variety of traits (pale, emaciated, sickly, etc). Why I don't just use "vampiric": As @chepner commented: I think the idea is to find a word that isn't so "circular", and doesn't refer explicitly to vampires or require knowledge of vampires in context. If someone were to ask "What does a vampire look like?", then "It looks vampiric/vampirish" wouldn't be terribly helpful. I don't want to explicitly refer to drug addicts as vampires. I just want to capture those traits in the best way. 
Answer: There is always the tried and true "strung-out" or "cadaverous" or "corpselike" i like "he had the look of a worn and deflated pillowcase in need of a wash".

Ex Output:
no

Question: English isn't my mother tongue, and when we recently talked to a native speaker (during some company audit), he pointed out that the plural word "trainings" is actually wrong (he pointed that it is a very common mistake and was almost amused by it). I couldn't understand why and wondered what the correct plural of "training" would be. Online Dictionaries/Thesaurus don't answer it, so it's probably another opinion-based statement. I haven't found a source to back it up, though. 
Answer: Training is both countable and uncountable. Usually, referring to a process, it is uncountable and has no plural. It is sometimes used to mean "a specific training event", and is then countable, and has the plural "trainings". The OED has examples of this use going back to 1578, with the plural recorded from 1598.

yes
