Miyagun ƙwayoyi suna da haɗari.

It is partly transparent, but it also works as a set phrase.

• miyagun = bad, harmful, or evil in the plural
• ƙwayoyi = pills, capsules, small particles, or in some contexts drugs

Together, miyagun ƙwayoyi commonly means drugs, especially illegal drugs or harmful narcotics. So yes, the words contribute to the meaning, but the whole phrase is more idiomatic than a word-for-word translation might suggest.

Mugu is the basic singular form meaning bad/evil person or bad/evil.

Here, the noun ƙwayoyi is plural, so the adjective also has to be plural. That gives miyagu.
When this adjective comes directly before a noun, it usually takes an extra linking -n, so you get miyagun ƙwayoyi.

So the pattern is roughly:

• mugu = singular/basic form
• miyagu = plural
• miyagun ƙwayoyi = plural adjective directly attached to the noun

ƙwayoyi is the plural of ƙwaya.

Depending on context, ƙwaya can mean things like:

• pill
• tablet
• seed
• grain
• small round piece

So ƙwayoyi can literally mean pills/tablets/seeds/small units. In this sentence, because of the full expression miyagun ƙwayoyi, it refers to drugs.

suna da literally means they have.

In this sentence:

• suna = they are / they do / they have depending on the structure
• da = with / have

So miyagun ƙwayoyi suna da haɗari is literally something like drugs have danger.
Natural English says drugs are dangerous.

This is very common in Hausa: a noun like haɗari (danger) is used where English might prefer an adjective like dangerous.

Because Hausa often expresses qualities with a structure like X na/ta/suna da + noun.

So instead of saying:

• X is dangerous

Hausa very naturally says:

• X has danger

That gives:

• suna da haɗari = they are dangerous

So haɗari is a noun meaning danger/risk, but the whole phrase functions like an English adjective.

The basic order here is:

• Subject: Miyagun ƙwayoyi
• Predicate: suna da haɗari

So the sentence is built as:

• Drugs
  • they have danger

This is a normal Hausa pattern. English uses to be + adjective very often, but Hausa often prefers structures like have + noun for this kind of meaning.

It includes the idea of they, but it is more than just a standalone pronoun.

In this structure, suna is the normal subject form used with plural subjects in the present/imperfective type of pattern. So it works as the agreement word for they.

That is why Hausa does not just say:

• Miyagun ƙwayoyi da haɗari

It needs the subject marker:

• Miyagun ƙwayoyi suna da haɗari

So for learners, it is safest to treat suna da as a useful chunk meaning they have / they are with.

These are special Hausa consonants.

• ƙ is not the same as ordinary k
• ɗ is not the same as ordinary d

A simple learner-friendly way to think of them is:

• ƙ = a stronger, more forceful k
• ɗ = a special Hausa d made differently from English d

You do not need perfect pronunciation immediately, but it is good to notice that Hausa spelling marks these sounds on purpose. They are real sound differences, not just decorative spelling.

A rough pronunciation guide:

• ƙwayoyi ≈ kway-oh-yee
• haɗari ≈ ha-da-ree, but with that special ɗ

It normally sounds like a general statement:

• Drugs are dangerous

Even though forms like suna can appear in present-time contexts, here the sentence is understood as a general truth or general warning, not just something happening at this exact moment.

A natural singular version would be:

• Muguwar ƙwaya tana da haɗari.

Here the changes are:

• miyagun → muguwar because the noun is now singular
• ƙwayoyi → ƙwaya
• suna da → tana da because the subject is singular

So the sentence changes its adjective form and its subject marker to match the singular noun.

Hausa does not use articles in the same way English does.

So a sentence like:

• Miyagun ƙwayoyi suna da haɗari

can be understood from context as:

• Drugs are dangerous
• The drugs are dangerous

In this case, it is most naturally read as the general statement drugs are dangerous. Context tells you whether something is definite or indefinite.
