analyses

1. 1
   noun

   Plural of analysis.

   The committee compared several independent analyses before reaching a decision.

   Recent chemical analyses confirmed the presence of lead in the soil.

   Note

   The singular's -is becomes -es here, the Greek pattern also seen in basis/bases and crisis/crises. Only the countable meanings take this plural: separate studies, their results, and chemical breakdowns of a substance. So a lab can run several analyses on one sample. Analysis as a field of mathematics, or as the study of musical structure, is uncountable and has no plural.

2. 2
   verb

   Third-person singular simple present indicative of analyse.

   The economist analyses spending data to forecast the next quarter.

   This software analyses network traffic for signs of intrusion.

   Note

   Here is the British spelling of the verb's -s form; American English writes analyzes, from analyze. Only in British spelling does it collide with the noun plural, and the surrounding words tell them apart. A subject in front marks the verb (the lab analyses samples). A determiner marks the plural noun (the analyses were checked).
