Using relationships words in English

This list moves relationship vocabulary into a more formal register, and with it come two pronunciation points that written study alone will never reveal. Separate is said differently as a verb and as an adjective, and conflict moves its stress depending on whether it is a noun or a verb. Both patterns are productive across hundreds of English words, so this page is a good place to meet them.

What to watch out for

Words learners mix up

Three tables: the family words that reach beyond the household, four verbs for a relationship coming apart and being put back, and four abstract nouns that do not all count the same way.

Family beyond the household: four precise words

WordWhat it actually meansIn a sentence
ancestorSomebody in your family from long before you were born. The opposite is a descendant.His ancestors came from Ireland.
guardianAn adult legally responsible for a child who is not their own. A legal role, not an emotional one.Her aunt became her legal guardian.
godmotherA woman who promises at a christening to take an interest in the child. Religious in origin, social in practice.My godmother sends a card every year.
widowA woman whose husband has died. The male equivalent is a widower, with the extra syllable.She has been a widow for ten years.

These four are precise in a way that everyday family words are not, and precision is exactly why they are useful in writing. Guardian in particular does real work on forms, where parent or guardian is the standard British phrase, and it is entirely separate from the newspaper of the same name.

Coming apart, and going back together

WordWhat it actually meansIn a sentence
splitInformal, and used about couples ending a relationship: they split up last year.The band split after their third album.
betrayTo break somebody’s trust deliberately. Strong, and it takes a person as its object.He felt betrayed by his closest friend.
forgiveTo stop being angry about what somebody did. Irregular: forgive, forgave, forgiven.She has never quite forgiven him.
reconcileFormal, and usually passive or reflexive: they were reconciled. It takes two sides, not one.The brothers were finally reconciled.

The structures differ in a way worth noting. Forgive takes the person directly — I forgive you — and the offence goes after for. Reconcile almost never appears in the plain active voice about people; English says they were reconciled rather than they reconciled themselves, and the everyday alternative is simply make up.

Four abstract nouns, and how English counts them

WordWhat it actually meansIn a sentence
loyaltyUncountable when it means the quality, though divided loyalties exists as a fixed plural.His loyalty to the team never wavered.
intimacyUncountable. It means closeness of any kind, not only the romantic sense learners expect.There was an easy intimacy between them.
lonelinessUncountable, and it names the feeling. Being alone is a fact; loneliness is what it does to you.Loneliness affects older people badly.
bondCountable, unlike the other three. You form a bond and it can be strong or close.They formed a close bond at university.

The distinction between alone, lonely and loneliness is the one worth fixing. Alone states a fact about how many people are in the room; lonely describes how that feels; and loneliness names the feeling as a thing you can write about. Plenty of people are happily alone, and that sentence is impossible if the three words are treated as one.

Collocations that sound natural

Six words that appear inside frames rather than on their own. Two of them take a preposition that has no equivalent in most other languages, which is why they go wrong so often.

Where each word belongs

Seven words that place you socially as much as they carry meaning. Relationship vocabulary is where the difference between a form, a conversation and a formal letter shows most clearly.

Sentences to try

Four frames at the formal end of the register. Say each aloud and check the stress on the two-syllable words.

Questions about relationships vocabulary

How do you pronounce "separate"?

It depends on the word class. The verb has a full final syllable: SEP-a-rate, rhyming the ending with rateWe separated the documents. The adjective reduces it to a weak vowel: SEP-ritThey live in separate houses. Many English words behave this way, with a strong -ate for the verb and a weak one for the noun or adjective: estimate, graduate, duplicate, moderate, deliberate. Getting it right is one of the clearest signs of an advanced speaker.

Why does "conflict" sound different as a noun and a verb?

Because English marks the difference with stress. The noun is CON-flict, with the emphasis on the first syllable: an armed conflict. The verb is con-FLICT, with the emphasis on the second: The two reports conflict. This pattern covers dozens of two-syllable pairs — a RE-cord but to re-CORD, an IN-crease but to in-CREASE, an IM-port but to im-PORT. The reliable rule is that the noun takes the front stress and the verb the back.

When should I use "sibling" instead of brother or sister?

Sibling is a formal, gender-neutral term that belongs in writing, forms, research and official contexts: Participants with three or more siblings… In ordinary conversation English speakers say brothers and sisters, and Do you have any siblings? sounds noticeably stiff. The same register gap applies to spouse against husband or wife, and to offspring against children. Choosing the formal word in casual speech is a subtle error, but a noticeable one.
