"Mereka perlu peralatan saya."

Translation: They need my equipment.

[Sam67858]

Should be ‘equipment’

[_adrianpop_]

Reminder:

• The prefix pe- and the affix -an are used to form nouns

• Peralatan means equipment

• The root is alat (noun) which means tool

• Other words with this root: mengalati (to equip), memperalat (to use as an instrument)

[joeldipops]

Equipment cannot be plural.

[SherleneKl]

why not, they need my tools?

[joeldipops]

I think that's the difference between "alat" and "peralatan", so alat would be any old simple tool, but "peralatan" must be a specialised set of things.

Should be "They need my equipment."
