Questions & Answers about Lapsuudessa minä olen aina onnellinen.
Why do we use the -ssa ending for childhood here, when seasons use different endings?
In Finnish, different periods of time prefer different location endings. While the four seasons typically use -lla/llä (like kesällä for 'in summer'), stages of life like lapsuus (childhood) use the 'in' ending -ssa/ssä. You are literally saying 'inside childhood'.
How does the word lapsuus (childhood) become lapsuudessa?
Words ending in -uus belong to a special word type. When you add an ending to them, the -s turns into -de-. So, the base word lapsuus becomes the stem lapsuude-, and then you add the -ssa ending.
Is the word minä (I) required in this sentence?
No, it is optional. You could simply say Lapsuudessa olen aina onnellinen. The verb form olen already tells the listener that 'I' am the subject. Finns frequently drop the words for 'I' and 'you' in both writing and speech.
The word onnellinen (happy) looks a lot like onni (luck/happiness). Are they related?
