For most verbs ending in 'y,' if the letter before the 'y' is a consonant, change the 'y' to 'i' and add 'es' or 's' for the third-person singular present. For example, "fry" in future tense ("will fry") changes to "fries" in the present tense for he, she, or it. However, if the letter before the 'y' is a vowel, just add 's.' For instance, "play" in future tense ("will play") becomes "plays" in the present tense. This inflection ensures that the verb aligns with the present tense while adhering to consistent spelling rules.
