EXPLANATION:
TENGO is the 1st person singular of the present of the verb tener and it ends in -go as it is an irregular verb.
Imperfect: the Past Tenses. In very general terms, the preterite tense is used to refer to a single event that happened at a specific point of time or had a specific duration in the past, while the imperfect tense is used to describe ongoing events or events without a specific time period in the past.
Well, in all languages, words are spelt differently. Because of this, you won't have the same words in two different languages having the same letters. For example, milk in English is spelt with 4 letters, but in Spanish, it is five (leche). Although there may be some words that share the same number of letters, this doesn't happen always. So, in this case, it was just how the language was created.
