What writing resource do you usually use to find specialized vocabulary definitions?

I typically use specialized dictionaries and glossaries, such as industry-specific dictionaries or academic databases, to find definitions of specialized vocabulary. Online resources like Merriam-Webster's Medical Dictionary or the IEEE Xplore digital library can also be invaluable for technical terms. Additionally, websites like Lexico or Vocabulary.com provide clear definitions and usage examples. These resources help ensure accurate understanding and application of specialized language in context.
