Learn Swedish: Vi läste motiveringen till nomineringen. - We read the justification for the nomination.

It's a false friend! While the verb motivera can mean both "to motivate" and "to justify," the noun motivering almost always means a "justification," "explanation," or "statement of reasons" (such as the grounds for an award). If you mean "motivation" in the sense of personal drive or enthusiasm, the correct Swedish word is motivation.

Why does the sentence use till instead of för to translate "for"?

In Swedish, till is frequently used to show a strong association or "belonging" between two nouns, much like "to" or "of" in English (for example, nyckeln till dörren - the key to the door). Motiveringen till nomineringen treats the justification as an essential part belonging to that specific nomination. Translating "for" directly as för here would sound unnatural.

Both motiveringen and nomineringen end in -ingen. How are these nouns formed?

These words are formed by taking verbs (motivera, nominera), dropping the final -a, and adding the suffix -ing to turn them into nouns. Nouns ending in -ing in Swedish are almost always en-words. Because this sentence requires the definite form ("the justification," "the nomination"), they both get the standard definite suffix -en, resulting in motiveringen and nomineringen.
