meaty
Word family
Synonym discussion
Sense: adjective/3
All four words describe something with depth or importance, but 'meaty' is the most informal and carries a vivid physical metaphor — it suggests content you can 'sink your teeth into.' 'Substantial' is the most neutral and widely applicable, describing anything with real size, value, or importance (a substantial donation, a substantial argument). 'Rich' focuses on density of detail or quality (rich data, rich texture), but can also imply abundance rather than depth. 'Weighty' conveys seriousness and often heavy responsibility (a weighty decision, a weighty document), lending a formal tone. 'Significant' emphasises measurable impact or statistical importance (a significant finding, a significant shift in policy). Use 'meaty' when you want an informal, enthusiastic way to praise a book, conversation, or article as being satisfyingly full of thought-provoking material. For example: 'We had a meaty discussion about urban planning' sounds lively and engaging, whereas 'a weighty discussion' would sound grave and formal.
Etymology
Formed from the noun 'meat' (which originally meant 'food' or 'solid food' in Old English) plus the suffix '-y', which turns nouns into adjectives meaning 'full of' or 'having the quality of'. The literal sense 'like or full of meat' has been in use since Old English times. The figurative meaning 'full of substance or interesting ideas' emerged in the 19th century, extending the idea of 'meaty' as something satisfying and substantial from food to the world of ideas.
