Compound word
This word is a compound made up of 'die Einnahme' (revenue/income) and 'die Quelle' (source). So it literally describes a 'source' from which 'Einnahmen' (income/money) flow.
EXAMPLE

Typical adjectives
Common adjectives combined with 'Einnahmequelle' (source of income) are 'wichtig' (important), 'zusätzlich' (additional), 'sicher' (secure), 'stabil' (stable), or 'die einzige' (the only).
EXAMPLE

Typical verbs
In keeping with the metaphor of a 'Quelle' (source), verbs such as 'eine Einnahmequelle erschließen' (to tap into/create a source of income), 'haben' (to have), or 'suchen' (to look for) are used. When a source of income ends, you can say it 'versiegt' (dries up).

Einnahmequelle vs Einkommen
income
'das Einkommen' and 'die Einnahmequelle' both have to do with money that you receive. 'Einkommen' means the sum of money itself, for example per month or per year. 'Einnahmequelle' means the source of this money, that is, how you get it, such as work, rent, or a business. The words can be confused because a source of income brings in income. A practical way to remember it: 'Einkommen' is the money; 'Einnahmequelle' is the path the money comes from.
Einnahmequelle
Die kleine Wohnung ist für ihn eine wichtige Einnahmequelle, weil er sie vermietet.
The small apartment is an important source of income for him because he rents it out.
Einkommen
Mein Nachbar hat ein festes Einkommen und kann seine Miete gut planen.
My neighbor has a steady income and can plan his rent well.
