Meaning at a glance

  • Primary sense: The secretion of milk from the mammary gland of a female mammal.
  • Grammar: lactation is listed as noun.
  • Nearest alternatives: breastfeeding, chyle, chylifaction, chylification.
  • Useful contrasts: agalactia, dry period.
  • Usage evidence: The World Health Assembly, the decision-making body of the WHO, wants to see at least 50 percent of the world's children under 6 months of age exclusively breastfed by 2025. Reaching that target will require an investment of an additional $5.7 billion, or just $4.70 per newborn, for such things as improving breastfeeding practices in maternity facilities and improving access to lactation counseling — and it could generate $300 billion in economic gains across lower- and middle-income countries by 2025 and save 520,000 children's lives in the next 10 years, according to a World Bank study.

Source and review context

This entry combines structured lexical data with WordToolSet review checks. Definitions, examples, synonyms, and usage notes may come from different source tables, so the page is designed to show evidence from more than one angle before you rely on "lactation" in a final draft.

If a word has several senses, prefer the sense that matches your sentence's grammar and surrounding context. A correct definition can still be the wrong choice when the sentence needs a different register, emphasis, or level of specificity.

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 "lactation" as the right word for your sentence.

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

Compare nearby meanings

  • Use synonyms when you need a softer, stronger, simpler, or more specific word.
  • Use antonyms to check the boundary of the meaning and avoid accidental contrast.
  • Use the example sentence to confirm the word behaves naturally in context.
  • Keep the original wording when a replacement adds complexity without improving precision.

Definition decision workflow

1. Identify the role

Check whether "lactation" is acting as 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 "breastfeeding" 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 "lactation", 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.
