I've just found Oxford Learner's Dictionary has this sentence:
Natural language is characterized by redundancy.
Nice to see it. From time to time, I've been feeling that what is so wrong about redundancy. Sometimes it makes the word easier to process or charming or emphatic. We are not CPUs.
Well, that said, this expression caught my eyes: If you need help beyond that, the doctor can recommend a referral. (from Abby's [https://www.arcamax.com/healthandspirit/lifeadvice/dearabby/s-2063872])
Question #1: Am I right in thinking 'the doctor' here means any doctor? -- There's no doctor appeared in the article.
Question #2: Am I right in thinking the 'recommend a referral' as redundancy?
