Short answer. Yes, an expert can give an opinion. Rule 130, Section 52 allows a witness's opinion on a matter requiring special knowledge, skill, experience, training, or education to be received in evidence, but only once that expertise is actually shown to belong to the witness who is testifying — the opinion is only as good as the shown qualification behind it.
What the law says
The opinion of a witness on a matter requiring special knowledge, skill, experience, training or education, which he or she is shown to possess, may be received in evidence.

The general rule and this exception
Ordinary witnesses are generally expected to describe what they personally perceived, not to offer conclusions drawn from specialized training. Section 52 carves out the exception that makes expert testimony possible at all: an opinion is admissible where the matter requires special knowledge, skill, experience, training or education — the kind of subject an untrained person could not reliably assess just from ordinary observation, such as a technical cause of a structural failure or a medical diagnosis.
What kind of subject matter qualifies
The rule's list is broad by design — special knowledge, skill, experience, training or education covers many fields, from medicine and engineering to accounting and handwriting analysis. What ties the category together is that the matter goes beyond what a layperson could reasonably work out on their own, which is exactly why the law allows a suitably qualified witness's conclusion, rather than just their raw observations, to reach the court.
The qualification has to be shown first
The section does not admit an opinion just because the witness claims expertise — it requires that the relevant knowledge, skill, experience, training, or education be shown to possess by that particular witness. In practice, this is why a party calling an expert lays a foundation first, establishing the witness's credentials, background, and relevant experience, before asking for the opinion itself; skipping that step leaves the opinion without the qualification the rule demands.
How this differs from an ordinary witness's testimony
An ordinary witness is generally confined to facts within their own personal knowledge — what they actually saw, heard, or otherwise perceived — and their opinions are usually restricted to a narrower category of everyday inferences. An expert witness under this section is allowed to go further and offer a genuine opinion or conclusion on a technical matter, precisely because their shown expertise is what the rule treats as the safeguard against speculation that would otherwise be excluded. That distinction is why qualifying a witness as an expert, before asking for an opinion, is not a mere formality but the very foundation the rule is built on.
