Ideas Synonym: Other Words for Ideas
Quick answer
Common synonyms for ideas include notions, concepts, thoughts, plans, proposals, insights, and brainwaves. Because ideas is plural, keep the replacement plural too, and choose by meaning: concepts for abstract ideas, plans for actionable ones, and insights for realizations.

Definition
noun (plural)
1.Thoughts, suggestions, or mental pictures of possible courses of action.

noun (plural)
2.Concepts or mental impressions formed in the mind.

noun (plural)
3.Opinions, beliefs, or views a person holds.

Keep the replacement plural
Because ideas is plural, the natural swap is also plural: notions, concepts, thoughts, plans. If you reach for an uncountable word like insight or inspiration, either keep it singular and rework the sentence (plenty of inspiration) or use the countable plural (fresh insights). Matching the number keeps the sentence clean.
Ideas vs concepts vs notions vs thoughts
These four are the closest, but they carry different weight. Thoughts is the most general: anything passing through the mind. Notions are lighter and often half-formed (vague notions). Concepts are more developed and abstract, the kind you can define and build on (the concepts behind the product). Ideas sit in the middle and lean toward things you could act on.
A useful test: the more shaped and usable the things are, the more concepts or ideas fits; the vaguer they are, the more notions or thoughts fits.
Words for fresh or original ideas
For ideas nobody has had before, the strongest words are innovations, inventions, and breakthroughs. For the moments they arrive, brainwaves, epiphanies, and revelations capture that sudden spark. In business writing, fresh ideas often becomes new initiatives or new approaches.
A formal alternative to ideas
In formal or academic writing, conceptions, notions, and propositions read more elevated than ideas. When the ideas belong to their maker, brainchildren is a vivid choice, though it is informal.
