Usage
Plural word for monkey The plural form of monkey is monkeys (not monkies). Words that end with a -y preceded by a vowel (a, e, i, o, u) are made plural by adding an -s at the end, as in chimney/chimneys and ray/rays. This can be confusing, because the plural form of words that end with a -y and are preceded by a consonant is made by changing the ending to -ies, as in party/parties, candy/candies, and duty/duties.

Etymology
Origin of monkey
First recorded in 1520–30; origin uncertain; possibly from Low German; compare Middle Low German Moneke (name of son of Martin the Ape in the story of Reynard the Fox ), equivalent to mone- (akin to obsolete French monne “she-ape,” Spanish, Portuguese mono “ape”) + -ke diminutive suffix
Explanation
A monkey is a tropical, long-tailed animal known as a "primate." If you visit India or Sri Lanka, you're almost guaranteed to see monkeys, but don't monkey around with them. Many monkeys live in trees, although some are ground-dwelling, and increasingly many live in urban areas, scavenging food and interacting with people. Monkeys are famously playful and mischievous, and because of this, monkey is a common diminutive (or fond nickname) for impish kids, and "monkey business" is foolishness or deceitful behavior. When you monkey around, or monkey with something, you fool about or fiddle with it.
