Jin daɗi na yana ƙaruwa idan na karanta littafi.

Word‑by‑word:

• jin – the verbal noun of ji (to feel, hear, sense); here: feeling of
• daɗi – pleasure, enjoyment, sweetness
• jin daɗi together – pleasure, enjoyment, feeling good
• na – my (possessive pronoun after a noun phrase)
• jin daɗi na – my pleasure / my enjoyment
• yana – he/it is …‑ing (3rd person singular continuous/progressive)
• ƙaruwa – verbal noun from ƙaru (to increase); increasing, increase
• yana ƙaruwa – is increasing
• idan – if / when / whenever
• na (before karanta) – 1st person singular I in the perfective (completed) aspect
• karanta – to read
• littafi – book

So a very literal gloss could be:

My pleasure is increasing when/whenever I (have) read a book.

Daɗi by itself means things like pleasure, enjoyment, deliciousness, comfort, fun depending on context.

Jin daɗi is a set expression built from:

• jin – feeling (verbal noun of ji)
• daɗi – pleasure

So jin daɗi literally is feeling of pleasure, and it is commonly used to mean:

• enjoyment
• feeling good / feeling happy
• having fun / taking pleasure in something

You can sometimes use daɗi alone (for example about food: abincin nan daɗi ne – this food is tasty), but for the more emotional or general feeling of enjoyment, Hausa very often prefers the phrase jin daɗi.

In this sentence, jin daɗi na is more natural than just daɗi na for “my pleasure / my enjoyment.”

Here na is a possessive pronoun meaning my that comes after the noun phrase:

• jin daɗi na – my pleasure / my enjoyment

Hausa has two main ways to show possession:

1. Suffix on the noun

   • daɗi → daɗina – my pleasure
   • So jin daɗina = my enjoyment

2. Independent pronoun after the noun phrase

   • jin daɗi na – literally pleasure of me → my pleasure

Both jin daɗina and jin daɗi na are possible in Hausa. The separate na is very common and especially handy when:

• the noun phrase is longer or more complex (jin daɗi sosai na, etc.),
• or for a slightly more colloquial or emphatic feel.

So in this sentence, jin daɗi na is perfectly normal; jin daɗina would also be understood as “my pleasure,” though many speakers would naturally say it the way given.

Yes. The basic structure is:

• [Jin daɗi na] [yana ƙaruwa] [idan na karanta littafi].

Breakdown:

• jin daɗi na – my pleasure → subject
• yana ƙaruwa – is increasing → verb phrase (predicate)
• idan na karanta littafi – when I read a book → conditional / time clause

So the thing that is increasing is my pleasure.

You could rearrange the clauses and say:

• Idan na karanta littafi, jin daɗi na yana ƙaruwa.

The meaning is the same; Hausa allows either order for the idan‑clause.

Yana is the 3rd person singular continuous/progressive marker, roughly he/it is …‑ing.

In Hausa, one very common way to make a progressive or ongoing action is:

subject + yana / tana / suna + verbal noun

So:

• yana ƙaruwa – it is increasing
• jin daɗi na yana ƙaruwa – my pleasure is increasing

If you say only jin daɗi na ƙaruwa, it sounds incomplete or ungrammatical in standard Hausa, because ƙaruwa is a verbal noun and normally needs that auxiliary (yana, tana, etc.) to make a finite verb phrase in this pattern.

To say it without the progressive structure, you would instead use the finite verb:

• jin daɗi na ya ƙaru – my pleasure increased / has increased

So:

• jin daɗi na ya ƙaru – completed event: my pleasure increased.
• jin daɗi na yana ƙaruwa – ongoing/habitual: my pleasure is (always) increasing.

ƙaruwa is the verbal noun (sometimes called a masdar) of the verb ƙaru.

• ƙaru – finite verb: to increase
  • ya ƙaru – it increased
• ƙaruwa – verbal noun: increase, increasing

Uses:

• With a progressive auxiliary:
  • yana ƙaruwa – is increasing
• As a noun:
  • ƙaruwa a farashi – an increase in price

So in the sentence, yana ƙaruwa literally is it is in a state of increasing, which is how Hausa builds the progressive aspect here.

Idan can mean both if and when/whenever, depending on context.

In this sentence:

• idan na karanta littafi – literally if/when I read a book

Because we are talking about a regular, habitual situation (every time I read, my pleasure increases), English normally translates this as:

• when I read a book or whenever I read a book

So the nuance here is whenever, not a doubtful “maybe” kind of if.

Here na is not the possessive my, but the 1st person singular subject + perfective aspect marker:

• na karanta – I read / I have read (completed action)

The pattern is:

• na karanta – I read
• ka karanta – you (m.sg.) read
• ta karanta – she read
• etc.

In idan‑clauses, Hausa often uses the perfective na karanta to describe:

• general or habitual situations,
• things that are true whenever something happens.

So idan na karanta littafi comfortably means:

• when(ever) I read a book
  rather than strictly past “when I read a book (once, in the past).”

Context tells us it is a general statement, not a one-time past event.

Yes, idan ina karanta littafi is grammatical, but the nuance shifts.

• idan na karanta littafi

  • uses perfective (na)
  • suggests whenever I read a book (as a complete act), my pleasure increases.
  • focuses on the act being completed.

• idan ina karanta littafi

  • uses continuous/progressive (ina = I am …‑ing)
  • suggests when I am in the process of reading a book, my pleasure increases.
  • focuses on the ongoing activity.

In many everyday contexts, both could be understood similarly, but idan na karanta littafi is the more typical, compact way to express a general whenever‑type condition.

Littafi by itself is singular and not explicitly marked for definiteness, so it can be understood as:

• a book (indefinite singular), or
• book(s) in general, depending on context.

In this kind of generic statement, littafi is usually interpreted as a book / books in general:

• My pleasure increases when I read a book / when I read books.

If you wanted to be clearly specific, you could say something like:

• idan na karanta littafin nan – when I read this book
• idan na karanta littafin – when I read the book (already known in context).

Yes. Both orders are natural in Hausa:

1. As given:
   • Jin daɗi na yana ƙaruwa idan na karanta littafi.
2. With idan‑clause first:
   • Idan na karanta littafi, jin daɗi na yana ƙaruwa.

The meaning is the same. Placing idan na karanta littafi first can slightly highlight the condition (“Whenever I read a book…”), but it is a stylistic choice rather than a big grammatical difference.
