Is it redundant to use the suffixes -ic and -al on the same word?

ie:
symmetric vs symmetrical
acoustic vs acoustical

these are the only two I can think of off the top of my head, but is becoming a pet peeve of mine and I'm was wondering if I am justified in my annoyance with this one guy at work.

lol, then elitist i shall be. but i'm just a dumbass engineer, what do i know?

Symmetrical seems more appropriate than acoustical, which I'm not sure I've ever heard.

1/3/2011 11:07:24 PM

^ acoustical tile?

1/3/2011 11:11:06 PM

you can't turn acoustic into an adverb by adding -ly, but you can do so with the other two.

So long as someone expresses a clear idea, who gives a fuck about grammar/spelling? Seems like a waste of brain space

It depends on the word and the usage. For example, "mystic" can be used as a noun, but "mystical" is definitely an adjective. I think that generally, the -al ending makes it serve as a predicate adjective modifying a verb like be or look; so to be economical, to appear symmetrical, etc.

You can be annoyed at whoever you want, because acoustical sounds terrible.

English is overly complex. That doesn't mean you have an excuse for fucking up though, asshole.

ok, so what you're saying is by convention this is not true for some words.

but what is the difference in "symmetric all wheel drive" and "symmetrical all wheel drive"
