Aline from Egypt asked about the noun equipment and why it isn't used in the plural form (*equipments).
Thank you for this question.
Equipment is a noncount noun, or a noun that cannot be counted and does not have a plural form. You can have "a lot of equipment," "more equipment," or "less equipment," but not "*six equipment."
Like other noncount nouns, equipment always takes a singular verb, as shown in this entry from Merriam-Webster's Learner's Dictionary:
equipment
[noncount]
1 : supplies or tools needed for a special purpose
The photographer came early to set up her equipment.
I'm looking for a hobby that doesn't require a lot of fancy equipment.
The doctor bought an expensive piece of medical equipment for his new office.
2 : the act of equipping someone or something
Not enough funds were provided for the equipment of the troops.
