"I do not like these situations."
Translation:No me gustan estas situaciones.
Yo no gusta is incorrect. The sentence we have here is literally "These situations are not pleasing to me." The subject is "estas situaciones" the verb is '"gustan" (3rd pers plural) and the Indirect object pronoun "me" is the recipient of the action. "Gustar" always takes an indirect object. Sentences like this are often translated as "I like, " as "I like chocolate," but the meaning is "Chocolate is pleasing to me = "Me gusta el chocolate"
Gracias por su ayuda. Your answer was specific and comprehensive and was of great assistance me. I shall endeavour to retain the essence of that idea.
Thankyouthankyouthankyou... gustar has put my head on sideways many times. Now I think I get it, @rspreng
Because the actual subject of the sentence, "situations", is plural. Therefore both the verb (gustan) and the demonstrative pronoun (estas) have to match that.
You always keep the pronoun with the verb, so 'no' must come before 'me gustan'.
