Compound noun: Office supplies.
Toimistotarvikkeet is shown in our example as the plural of toimistotarvike. It comes from toimisto, which means office. Toimisto, in turn, comes from toimi (“chore, task, activity”) plus the suffix –sto, which forms collective nouns out of simple nouns.
Tarvike comes from the noun tarve (”need”) plus the suffix -ke, which can be used to produce diminutive forms of nouns. Tarvike would then be ”something that is needed.”
