Foreign Loan Letters

Letters which have previously been included in the Soewandi Spelling as foreign loan letters, are officially used in the EYD Spelling.

Letters	Example	English Meaning
f	maaf, fakir	sorry, poor
v	valuta, universitas	currency, university
z	zeni, lezat	engineer, delicious

Q and X

Letters 'q' and 'x' are still used in scientific subjects.

Example:

• a:b=p:q
• Sinar-X (X-ray)

Affixes and Prepositions

The writing of di- and ke- (affixes) can be distinguished from di and ke (prepositions), where di- and ke- is written together with the words that follow it, for example diambil, kehendak (is being taken, desire), while di and ke is written separately with the words that follow it, for example di rumah, ke pasar (at home, to the market). This is different to the former Soewandi Spelling, where both di- and di are written together with the words following it.

Repeated Words

Repeated words, mostly used in plural form of words, have to be fully written with letters, so the use of number "2" as used in the Soewandi Spelling is no longer valid.

Soewandi	EYD	English Meaning
anak2	anak-anak	children
ber-main2	bermain-main	to play around
ke-barat2-an	kebarat-baratan	westernized
