    Irregular plurals

    Generally speaking, going from the singular form to the plural one is quite simple: simply add an -s to the singular. 
    - a table => tables ; an orange => oranges. 

    There are 

    Some special endings: 

    A) Words ending with "Y"

    🔹 If the Y is preceded by a vowel ( a, e, i, o, u, y.) the  plural is in - s.
    a day=> days; toy => toys.

    🔹 If the Y is preceded by a consonant: the plural form is in -ies.
     - a spy=> 2 spies( espions) ; a country= 2 countries. 

    B) Words ending with -s, -sh, -ch, and -x  and some words ending with -o. (plural forms in -es.
    - a match => 2 matches;  a flash=> 2 flashes; a mass=> 2 masses; a tomato=> 2 tomatoes. 

    C) Words ending with -f  which have their plurals in  -ves:             

     a calf->calves a self->selves
     a knife->knives a loaf->loaves
     a leaf->leaves a wife->wives
     a life ->lives awolf->wolves    

    Some other words ending with -f have a regular plural: 
    roof => roofs; cliffs ; chiefs. 

    D) The words "deer", "fish" and "sheep" have no "s" in the plural. 
    one sheep => two sheep => a herd of sheep

    E) A few words have a different form of plural, or don't change from singular to plural: 

     a man 2 men a woman 2 women
     a foot 2 feet a tooth 2 teeth
     a child 2 children a mouse 2 mice
     a crisis 2 crises a criterion 2 criteria
     a species 2 species a means 2 means

    Some of these words have Greek or Latin origin:

    - the endings in -on have their plurals in -a:  criterion, phenomenon => criteria, phenomena.

    - the endings in -is have their plurals in -es:  a basis, thesis, hypothesis, analysis => bases, theses, hypotheses, analyses.
