|KOTUS type 29 (lapsi)||NSK types 45 (lapsi), 46 (hapsi) and 50 (uksi)|
A very small number of nominals ending with a hard consonant followed by -si. No consonant gradation.
The word lapsi is the only word always declined like this. A few other words may decline either like lapsi or like ovi (the two declensions differ only in the partitive singular and genitive plural).
Inflectional stem replaces -i with -e-. -e- of stem dropped before plural marker -i-.
When the partitive singular ending -ta/-tä and genitive plural ending -ten are attached, the consonant before the s is dropped. Genitive plural ending -en also possible. Partitive plural ending -a/-ä.
