What colour is it?

[dialog80]

Which sentence is true?

A frog is yellow.

The frog is yellow.

Give reasons for your answers.
Thank you.

A frog is yellow = all frogs are yellow. We think about each and every
individual frog.

The frog is yellow = We think about frogs as a group/ class of animals. It is
not necessarely true for each and every frog.

Frogs are yellow = Either of the above definitions.

> A frog is yellow.
False.
Being yellow isn't absolutely necessary for a frog to deserve the name "frog."

> The frog is yellow.
It's true only when the speaker means one specific frog that happens to be
yellow. Otherwise it's false.

Simple leap frog

at...

[Gość: fafik]

Actually, what is bothering me is the characteristic feature of any frog that
you could ever imagine.

What does the idea of frog mean?

[Gość: ms jones]

Frog \Frog\ (fr[o^]g), n. [AS. froggu, frocga a frog (in
sensel); akin to D. vorsch, OHG. frosk, G. frosch, Icel.
froskr, fraukr, Sw. & Dan. fr["o].]
1. (Zo["o]l.) An amphibious animal of the genus Rana and
related genera, of many species. Frogs swim rapidly, and
take long leaps on land. Many of the species utter loud
notes in the springtime.

Note: The edible frog of Europe (Rana esculenta) is
extensively used as food; the American bullfrog (R.
Catesbiana) is remarkable for its great size and loud
voice.

2. [Perh. akin to E. fork, cf. frush frog of a horse.]
(Anat.) The triangular prominence of the hoof, in the
middle of the sole of the foot of the horse, and other
animals; the fourchette.

3. (Railroads) A supporting plate having raised ribs that
form continuations of the rails, to guide the wheels where
one track branches from another or crosses it.

4. [Cf. fraco of wool or silk, L. floccus, E. frock.] An
oblong cloak button, covered with netted thread, and
fastening into a loop instead of a button hole.

5. The loop of the scabbard of a bayonet or sword.

Or did you mean this:

Meet Tim; he's a hot-blooded American guy who's looking for a one-night stand.
Unfortunately, Tim

Are you trying to figure out the generic meaning of articles or define the
meaning of "frog?"

[yoric]

Ah... so you're on a hunt after

"the property common to all frogs, and only frogs". But that's a question
philosophers had asked until Wittgenstein who, roughly, said there were no such
properties for most things (probably including frogs).
If that's what you're looking for, the problem is called categorisation.
