 Choosing just one word to describe someone who doesn't give up easily is difficult, as there are many nuanced options that capture different aspects of this quality. Here are some suggestions, with slight variations in emphasis:

Positive connotations:

• Tenacious: Firmly persistent, not easily yielding.
• Resilient: Able to recover quickly from setbacks.
• Determined: Firmly resolved to achieve something.
• Gritty: Having courage and resolve; persevering despite hardship.
• Indomitable: Unable to be defeated or subdued.

Neutral connotations:

• Persistent: Continuing firmly or steadily despite opposition or difficulty.
• Relentless: Unceasing or determined, especially in pursuit of something.
• Unyielding: Not giving way or submitting to pressure or force.
• Stubborn: Firmly fixed in purpose or opinion; not easily persuaded.

Negative connotations (use with caution):

• Obstinate: Unreasonably or blindly determined.
• Dogged: Undeterred and persistent, often in a way that is annoying or tiresome.
• Inflexible: Unwilling or unable to change or adapt.

The best word will depend on the specific context and the qualities you want to emphasize. For example, "tenacious" suggests strong will and resolve, while "resilient" highlights the ability to bounce back from adversity.

Ultimately, choosing the right word is a matter of personal preference and how you want to portray the person's determined nature.
