• Alternative Forms: Abbreviations and their expansions — the same word said at a different length (e.g., "TV" ↔ "television", "thousand" ↔ "one thousand")
• Synonyms: Different words with similar meanings (e.g., "street" ↔ "road", "mad" ↔ "angry", "big" ↔ "large")
• Spelling Variants: The same word spelled differently (e.g., "gray" ↔ "grey", "donut" ↔ "doughnut"). These carry a full paradigm of their own and live in the Spelling Variants card below, not here.

Each variant carries its own full set of forms, such as "grey", "greyer", and "greyest" for a spelling variant. Selected person words can also have male and female variants, such as "actor" and "actress". The ordinary translation remains the default when the person's gender is unspecified.
