Simple does not mean childish

Plain language respects the reader’s time. Specialists also benefit from a clear starting point before they examine nuance, usage notes, or technical detail.

Use the right level of detail

For everyday comprehension, the central meaning may be enough. For writing, translation, or specialized decisions, follow it with examples and an authoritative full dictionary entry.
