Understanding why intensity becomes intensitied 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 intensitied 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 intensitied to the store." The past tense form does not change based on the subject — I intensitied, you intensitied, he/she intensitied, we intensitied, they intensitied.
