The difference between was and des lies in how they are used in grammar. Was is the past tense of the verb to be, while des is the past tense of the verb to have.
The verb “to be” is used to describe or identify places, people, and things. Was signifies a single event that happened in the past, or a state of being that existed in the past. For example, “He was tired.” This sentence implies that at one point, he was tired, but he may not be tired anymore.
The verb “to have” is used to indicate possession, or ownership. Des is used to describe a state of possession that existed in the past. For example, “She had a pet dog.” This sentence implies that she used to own a pet dog, but she may not have it anymore.
In conclusion, was is used to describe events or states of being that happened in the past, while des is used to describe possessions that existed in the past. It is important to note that these three words can also be used in the present and future tenses as well. Knowing when to use each is a vital part of becoming a master of the English language
