Plural forms only!

Today's question - How many words can the forums think of that only exist in the plural form?

For example, the word scissors can only be in the plural form.

Excellent - Woody can you think of any more?

Woodward, I can understand that 'cattle' is 'plural' because it refers to several animals, but why the other words like 'scissors' are considered 'plural'? To me they are just words that end by 's' as much they are naming things which have two parts but they are only one thing, the half of 'trousers' is nothing, the half of 'glasses' is nothing while a part of the cattle is something, and to get 'plural' you have to have more than a thing.

I am saying something weird? Maybe there is a formal linguistic word to call theses kind of plurals like 'semi-plural' or 'odd-plural' he he or 'godwhatakindofpluralisthis' Sorry. Tell me please, I think there is one but i don't remember.

To have a 'plural' you have to have more than a thing is not necessarily True.
Some words are considered only in a plural form. Normally before these words you can say:
a pair of glasses or a pair of trousers but in reality you are talking about one.
These are just one of the many exceptions that exist in English. The specific name of the plural...I don't know if there is a specific word for it.
Consider your own language, Spanish. Isn't it the same in that too. You refer to one thing though you say it in plural.
The following nouns are always considered/said in plural form even though we are talking about 'one':
clothes pants pyjamas trousers binoculars glasses pliers scales scissors shears savings earnings surroundings stairs premises valuables ... ...

Arabic has dual forms. Trying to conjugate verbs is a nightmare!
