Note
The plural follows the regular spelling rule for nouns ending in a consonant plus y: the y becomes ies, so laboratory becomes laboratories. What it counts depends on which meaning of the singular is in play. It may be rooms equipped for research, whole research institutions, or places where chemicals, drugs or microbes are made. Several laboratories may therefore be rooms along one corridor or separate sites across a country.
