* Short Vowel Sound: The vowel "o" in "crop" makes a short vowel sound, similar to the "o" in "hot" or "stop".
* Long Vowel Rule: The "long vowel" rule typically applies when a vowel is followed by a consonant and then a silent "e" (like "hope", "bike", "time"). This is not the case in "crop".
Therefore, "crop" is a short vowel word.
