When expressing uncertainty or speculation, the phrase "seem like" can be quite useful. However, using it repeatedly throughout a piece of writing can become repetitive. Luckily, there are plenty of synonyms to use instead. For example, "appear" carries a similar connotation but can add a bit of sophistication to your writing. "Resemble" is another option and emphasizes the similarities between two things. "Suggest" is useful when implying a connection but not stating it outright. "Sound" can be used when discussing a person's tone or voice. And finally, "look" is a versatile synonym that can be used in a variety of contexts. By employing these synonyms, you can add variety and nuance to your language.
