Main Translations

• English: Decade
• Thai: ทศวรรษ (Sot-wan)
• Phonetic: dtà-sà-wàn (using standard Romanization for ease of pronunciation)
• Detailed Explanation: In English, "decade" refers to a period of ten years, often used to discuss historical events, cultural shifts, or long-term trends. It carries neutral emotional connotations but can evoke nostalgia or reflection when referencing past decades (e.g., the 1990s). Semantically, it is precise for time measurement, commonly used in formal contexts like history, business, or demographics. Usage scenarios include marking anniversaries, analyzing economic data, or discussing pop culture evolution.
• Thai: 10 ปี (Sip pee)
• Phonetic: sìp bpèe
• Detailed Explanation: In Thai, "10 ปี" is a more literal and informal translation, directly meaning "ten years." It lacks the formal nuance of "ทศวรรษ" and is often used in everyday conversations. Emotionally, it can imply routine or longevity, such as in personal milestones. Semantically, it is less specific to structured periods and is versatile in scenarios like casual storytelling or planning, but it may not carry the historical weight of "ทศวรรษ" in academic or official Thai discourse.
