I thought there were 9, which is what the NAB lists in Gal 5:22. However, I noticed that the old D-R lists 12, so I checked my Greek OT, and it lists 7 words. Some of those words have multiple, but similar, possible meanings, which may be why there are extras listed in different translations.

Just wanted to know if there is an 'official' list.

There are 7 gifts and 12 fruits, no?

The Baltimore Catechism gives 12.

Probably because they were published at a time when the approved translation in this country was the D-R.

For the fruit of the Spirit is

love
joy
peace
longsuffering
gentleness
meekness
goodness
temperance
faith

against such there is no law

So, stand fast therefore in the liberty
wherewith Christ has made us free
and be not entangled again
in the yoke of bondage

The Gifts and Fruits of the Holy Spirit
CCC 1830 The moral life of Christians is sustained by the gifts of the Holy Spirit. These are permanent dispositions which make man docile in following the promptings of the Holy Spirit.

1831 The seven gifts of the Holy Spirit are wisdom, understanding, counsel, fortitude, knowledge, piety, and fear of the Lord. They belong in their fullness to Christ, Son of David. They complete and perfect the virtues of those who receive them. They make the faithful docile in readily obeying divine inspirations.
Let your good spirit lead me on a level path.
For all who are led by the Spirit of God are sons of God . . . If children, then heirs, heirs of God and fellow heirs with Christ.

1832 The fruits of the Spirit are perfections that the Holy Spirit forms in us as the first fruits of eternal glory. The tradition of the Church lists twelve of them: "charity, joy, peace, patience, kindness, goodness, generosity, gentleness, faithfulness, modesty, self-control, chastity."

The Twelve Fruits
of the Holy Spirit
Charity
Joy
Peace
Patience
Kindness
Goodness
Generosity
Gentleness
Faithfulness
Modesty
Self Control
Chastity

The gentleman narrates the fruits of the Holy Spirit. He mentions Twelve Fruits.

The Latin Vulgate mentions 12. The 64 thousand dollar question is why, since the Greek NT only list 9? To complicate things, CCC #1832 lists 12, but CCC #736 lists 9. Jerome may be the only one who knew.

Your Greek (NT, I assume ) is confusing you because the verse break is in a different place than it is in English. The last two gifts are the first two words of verse 23. I have no idea why.

Compendium of the Catechism, 390, lists twelve fruits with indication that was from Vulgate version, I.e., Galatians 5:22-23, Vulgate.

Russian version of the Compendium indicates that Vulgate word since the actual Russian Bible gave just nine.

The Catechism of the Catholic Church in 1832 also mentions the word Vulgate.

Nova Vulgata Bible now lists just nine instead of twelve for Gal 5:22-23.
