Stress

The main rule is: the vowel before the last consonant or "y" is stressed:

máta — mother
suóla — sole (of footwear)
matéria — matter
nóve — new
kórdia — heart
aktór — actor
aván — forward
krokodíl — crocodile
dúmi — to think
jámi — to gather
báya — bay (in coast)
jaopáy — signboard

In words of the shape (C)CVV like háo — good, well, krái — to cry the first vowel is stressed.

In the combinations "au", "eu" — "u" is not stressed:

áusen — outside
áudi — to hear
áuto — car
máus — mouse
káusa — cause
éuro — euro

In the combinations "ai", "ei", "oi" — "i" is not stressed:

máini — to mean
fáil — file
bréin — brain
méil — mail
asteróida — asteroid

There are 4 consonant endings which are never stressed. These are -en, -us, -um, -er:

ínen — inside
íven — even
désnen — to the right of
vírus — virus
fórum — forum
sírkum — around
ínter — between
kompyúter — computer

The endings of nouns and adjectives -ik-, -ul- are unstressed:

gramátika
pedagógika
públika
Áfrika
Amérika
polítike
lógike
únike
psikológike
stímula
ángula

This doesn't apply to compound words with -fula like handafúla handful.

Non-standard stress is indicated through a doubled vowel:

kwantitaa — quantity
kwalitaa — quality
(and all abstract nouns derived from adjectives via the stressed suffix -(i)taa)
namastee — hello
adyoo — good-bye
bifoo — before
malgree — in spite of
shosee — highway
milyoo — milieu

The use of a doubled vowel is justified by that the stress in LdP is basically quantitative. A doubled vowel in a word without other vowels (like in 'zoo') is not regarded to be a stress mark.

Stress and word formation

In any derivation the stress of the basic word isn't shifted. It means that, for example, the plural endings -(e)s, the adverb suffix -em and the noun suffix -ing do not change stress:

kórdias — hearts
naturálem — naturally (from naturále — natural)
físhing — fishing (from físhi — to fish)

Only few suffixes beginning with a vowel are exceptions to this rule:

-isi, -ifi (glúbe — glubísi, glubífi)
-inka (snéga — snegínka)
-ina (dóga — dogína)
-ista (dénta — dentísta)
-(t)ive (ákti — aktíve)
-ale, -are (ménta — mentále, pol — poláre),

as well as the aforementioned stressed suffix -(i)taa.

Compound words retain the stress of their components:

auslándajén — foreigner
jánmalánda — native land, homeland

Suffixes beginning with a consonant may receive a secondary stress:

gínalík — womanly (from gína — woman)
kúsishíl — tending to bite (from kúsi — to bite)
ófnitúl — opener
vídibíle — visible
