How to make plurals?

Pluralisation in English can be a bit of a tricky game,
and as with any language the key to mastering this aspect lies in practicing through reading and conversing until the variations that appear unpredictable in the beginning become second nature, a matter of habit.

Having said that, there are certain principles that are generally applicable that make the task easier by giving us a broad idea of how common words are pluralised. Let us take a look at these.

For most nouns, add an 's' at the end of the word.
