Before you rely on this definition

Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "martian" as the right word for your sentence.

If your draft is formal, technical, persuasive, or sensitive, compare "martian" with a nearby alternative so the final choice matches both meaning and reader expectation.

Definition decision workflow

1. Identify the role

Check whether "martian" is acting as adj, name, noun in your sentence. A definition is only useful when the grammar matches the way the word is being used.

2. Test the nearest option

Compare it with "alien" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.

3. Confirm with context

Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.

Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.

Final meaning check

Before publishing a sentence with "martian", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.

When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.

Accordingly, during the greater part of the Martian day, the hoar frost and whatever light snow might have fallen on the preceding evening would be completely dissolved away, and thus the ruddy earth or the greenish ice-masses of the so-called oceans would be revealed to the terrestral observer."
