IPA: /nɒnˈrɪːjuːzəbl/
KK: /nɑnˈriːjuːzəbl/
Something that cannot be used again after its initial use.
Many products are designed to be nonreusable, which can lead to more waste.
Nonreusable → It is formed from "non-" (meaning not) and "reusable" (from "re-" meaning again and "usable" from Latin "uti" meaning to use). The word "nonreusable" means not able to be used again.
Think of 'not' ('non-') being added to 'usable' which means something can be used again. This helps you remember that 'nonreusable' refers to something that cannot be used again.
