Learn Polish: To tylko krótkoterminowe rozwiązanie. - This is only a short-term solution.

It is built from the adjective krótki (short) and the noun termin (term or timeframe). In Polish, when combining two words to form a compound adjective, they are typically joined by the linking vowel -o-. The adjective suffix -owe is then added to the end.

Why is krótkoterminowe written as one solid word instead of with a hyphen?

We write it as one word because the two parts are not equal. The first part (krótko) directly describes or modifies the second part (terminowe) — it means a short term. You only use a hyphen when both components carry equal, independent weight, such as in the word biało-czerwony (white and red).

Why does krótkoterminowe end in -e in this sentence?

Compound adjectives decline exactly like regular adjectives. It ends in -e because it must agree with the neuter noun rozwiązanie in the nominative case. If it were modifying a masculine noun, the base form would be krótkoterminowy.

Why is there no verb like jest (is) in this sentence?

In Polish, the verb jest is very often dropped in sentences starting with the demonstrative pronoun to when identifying or commenting on something. Saying To jest tylko krótkoterminowe rozwiązanie is also completely correct, but omitting the verb sounds very natural and concise.
