On the Loose Words

I mean, a lot of words are being used loosely. I can't think of a lot, but have collected some so far. My vocabulary closet is not that rich anyways, and it's hard to come up with all these words especially when it's so full of other dirty things. LOL.

Was at a tutorial discussing about obsessive compulsive disorder when this idea came in. "Obsessed" or "Obsessive", although with just the addition of a suffix, in psychiatric medical point of view, means something deeper than what we understand the word in English.

English:

excessive, esp. extremely so.

Psychiatric medicine:

1. recurrent and persistent thoughts, impulses, or images that are experienced, at some time during the disturbance, as intrusive and inappropriate and that cause marked anxiety or distress
2. the thoughts, impulses, or images are not simple excessive worries about real-life problems
3. the person attempts to ignore or suppress such thoughts, impulses, or images, or to neutralize them with some other thought or action
4. the person recognizes that the obsessional thoughts, impulses, or images are a product of his or her own mind (not imposed from without as in thought insertion)
   

And a classmate of mine asked about something naive, "What about obsession towards person of the opposite sex?"

The whole class broke into laughter for the next 5 seconds before the tutor wiped his tears and said, "Hey! Don't mix your personal interest into the matter. I don't care who you're obsessed with, that's your problem." And we laughed again.

Having said that, there are some other terms which I came across, used in English, but in psychiatric medicine, means something more than what it seemed, and might require medical treatment.

For example.

Anxiety.

Depression.

Or what I saw in another blog written by a lawyer, "Tourette Syndrome", by medical definition, is an illness.
