Lesson Generalization
The ory suffix often follows the letter t. The suffix is easy to hear and identify when pronouncing ory words of four or more syllables. In ory words of three syllables, careless pronunciation can make the suffix hard to hear.

say his-tor-y not his-try
say vic-tor-y not vic-try
say fac-tor-y not fac-try

Mnemonic device: Think of The tory Story when you write ory words.
