Hi, there, students!
Foam,
froth,
lather,
suds,
scum,
and spume
So these are all similar, but slightly different.
So…
Shaving foam:
you take it out of a can and put it on your beard or your face and shave.
That's a foam.
Polystyrene foam: I get the idea foam is something that's full of bubbles.
You have bath foam, as well, you put it in your bath.
Froth. I think you get on the top of a liquid.
So, if you have a cappuccino, the froth is really tasty.
Lather
You take a piece of soap and you start rubbing it, and it lathers;
it creates froth, foam, suds. And I think suds is probably the best word here
So, to lather is the actual process of taking
soapy water and rubbing them together
Suds
The first collocation that comes to mind is the phrase "soap suds"
and I think suds are for washing, it's the foam, it's the lather on the top
which comes from your soap.
I have a feeling suds are quite light
Now, what about scum?
When all the foam, all the suds have gone,
you got this piece… this thing floating on the water
it's like solid or very thick greasy liquid.
That is scum.
If you have a bath when you're really really dirty,
and then you take the plug out and the water goes out,
you might see a ring of scum around the edge of the bath.
Scum is pretty horrible. All the others: foam, froth, lather and suds, these are quite positive.
Okay, what about this last one: spume?
Spume is much more specific.
You know the waves on the sea that roll but, when there's a wind
and the wave comes up, the wind blows some of the water off:
"white horses". And that spray is called spume.
So it's the wind blowing the tops of the waves…
And that is spume.
So, let's go back again.
Foam: I think foam gives me the idea of something chemical
You might use it for the top of your cappuccino, but I think froth is much better.
He was frothing at the mouth.
I've got the idea with froth… is you got liquid and some sort of foam
Lather: I would use it more as a verb: this soap won't lather;
it won't make foam or froth or suds.
Notice, I'm using all of the words interchangeably and I think, with each of these definitions,
it's like a circle and one is better for one and one is better for another use.
Suds: to me, definite talk about soap suds and washing
and this froth on the top of the water which you get when you you are washing:
maybe with soap, or when you're washing your clothes,
or even when you're washing the dishes, yeah… you know, these little bits on the top
Scum: is when the soap and all the dirty fatty particles
have mixed together… and it's like a residue.
And if it's liquid enough, it'll go down the drain, but scum is really not…
If you don't clean the bath ever, It's gonna be covered in scum.
They also use this word, scum, to say that somebody is horrible,
this person is the worst of the worst.
So, if you call someone "scum", then that's a pretty strong insult.
These people are sheer scum!
And then the spume: this is the wave, and the wind blowing the top of it and spraying…
"White horses"
So, maybe bath foam, maybe shaving foam,
the froth on the top of your cappuccino.
He was frothing at the mouth. He was going crazy.
To lather
He's in a lather about that. He's very upset about it.
Suds: soap suds, something when you're washing, particularly on the top of water, like a froth.
Scum: this residue, this dirty horrible residue that you need to wash away.
And then spume: from the top of the waves.
Anyway, enough of that.
