The word turtlelike can be used to describe someone or something that moves slowly, cautiously and steadily. However, if you are looking for synonyms to avoid repetition, here are some options to consider. Tardily suggests moving slowly and deliberately, while languorous implies a relaxed, almost lethargic movement. If you are looking for more colorful language, you could use sluggish to describe a lethargic, slow-moving person, or ponderous to describe something that moves with great weight and deliberation. Finally, if you are looking for more positive connotations, you could use deliberate or unhurried to emphasize the idea of taking things slowly and carefully.
