Understanding why preliminary becomes preliminaried helps with spelling and pronunciation. Verbs ending in a consonant followed by -y change the -y to -ied in the past tense form.
When using preliminaried in writing, remember that it functions as a past tense verb and typically appears with time markers like yesterday, last week, or ago. For example: "Yesterday, she preliminaried to the store." The past tense form does not change based on the subject — I preliminaried, you preliminaried, he/she preliminaried, we preliminaried, they preliminaried.
