Is tropical a proper noun

Answer 1

Oh, dude, like, no way! "Tropical" is not a proper noun. It's just an adjective describing something related to the tropics. So, like, you won't see it starting with a capital letter unless it's at the beginning of a sentence.

Answer 2

No, the word tropical is an adjective, not a noun.

An adjective becomes a proper noun when it is the name of a specific person, place, thing, or a title; for example:

• Tropical Princess Beach Resort & Spas, Dominican Republic
• Tropical Storm (residential street), San Antonio, TX
• TDR, a Special Programme for Research and Training in Tropical Diseases, based at the World Health Organization (WHO), sponsored by the United Nations Children's Fund (UNICEF), the United Nations Development Programme (UNDP), and the World Bank.
• "Tropical Convergence", a novel by Melissa Good
