Singapore citizen / warded

Singapore citizen is acceptable, as would be Singaporean citizen. I am not at all familiar with such a use of ward as a verb--it is usually employed to mean that something or someone is fended off. Perhaps this is a British usage, and someone will come along who can give you an authoritative answer.

"ward
/wɔːd/

verb
past tense: warded; past participle: warded
1.
admit (a patient) to a hospital ward."

Terms like Singaporean, Liverpudlian and Sotonian are used over here but not really in formal situations. Your example would be either a 70 year-old male Singapore citizen or 70 year-old male Singaporean.

I prefer the first example, the one in the text, not only does it sound better, but other people can have difficulties with words like Singaporean, Liverpudlian or Sotonian. Singapore citizen is clear, and likely to be understood by everyone.

I would only call myself a Sotonian when talking to other people from the UK, with everyone else I say I'm from Southampton.

Many thanks, Miss Toad.
May I know which dictionary you referred to?

Miss Toad, could you please let me and hence other members, especially non-native speakers, as well as native speakers know your source which defines "ward" as "hospitalise"?

I and other members, I am sure, will appreciate it very much if you could reveal which dictionary you had referred to.

Miss Toad,
I have found out the name of the dictionary.

It is the Oxford Advanced Learners Dictionary. It is a thick dictionary. It is not cheap, to me.

IMHO, we should share our knowledge. That is one of the purposes of this forum.

Miss Tan, long ma jing san, keep those excellent questions coming.

I couldn't find that definition again when I looked; well researched.

Newspaper articles written by journalists whose second language is English may not be the best way to continue your English language education.

Perhaps classic English novels would be a better source.

Dare I suggest that you post your writing for us to analyse and discuss?

In any case, all the best.

The dictionary is the New Oxford Dictionary of English. It is thicker than the one I mentioned earlier. I have both dictionaries.

I don't think the first dictionary is easily available. I cannot find it in the book shop I bought it at any more. So, for those who are able to buy it, I am happy for them. That dictionary contains a lot of words, including words which are not standardised. For example' "ward", meaning "hospitalise" is not a recognised word in standard English, yet it can be found there but not in any other dictionaries.
