The 5 Love Languages: The Secret to Love That Lasts by Gary Chapman is a best-selling book that explores the idea that people express and receive love in different ways. Chapman identifies five "love languages," or primary ways individuals communicate love:

1. Words of Affirmation: Verbal expressions of affection, appreciation, encouragement, or compliments.

2. Acts of Service: Actions that demonstrate care and thoughtfulness, like helping with chores or running errands.

3. Receiving Gifts: Thoughtful gestures or presents that symbolize love and appreciation.

4. Quality Time: Giving someone your undivided attention, such as engaging in meaningful conversations or shared activities.

5. Physical Touch: Expressing love through physical gestures, like hugs, hand-holding, or cuddling.

The book emphasizes that understanding your partner's primary love language—and learning to speak it—can help build stronger, more fulfilling relationships. It offers practical advice, real-life examples, and tools for identifying both your own and your partner’s love languages, with the ultimate goal of fostering deeper emotional connections.
