Artificial language decoding — select the word that could mean “baseball” Given translations: • aptaose = first base • eptaose = second base • lartabuk = ballpark Which constructed word could stand for “baseball”?

Introduction / Context:
We must combine the stems for “base” and “ball”. The examples give “ose” for base (from “first/second base”) and “larta” for ball (from “ballpark”). The aim is to put these together without importing unrelated morphemes like “buk” (park) or ordinal prefixes.

Given Data / Assumptions:

• aptaose = first base → “ose” = base.
• eptaose = second base → confirms “ose”.
• lartabuk = ballpark → “larta” = ball; “buk” = park.

Concept / Approach:
Construct “baseball” by combining the base stem and the ball stem: “ose” + “larta”. Order is immaterial in many artificial-language items, but the option list offers an exact concatenation “oselarta”. We avoid “buk” since that means park, not part of baseball.

Step-by-Step Solution:

Verification / Alternative check:
“oselarta” maps cleanly to “base” + “ball”. Any inclusion of “buk” would shift meaning toward “park”, and ordinal prefixes like “apta/epta” are not part of the target concept.

Why Other Options Are Wrong:

• buklarta: “park-ball” → ballpark, not baseball.
• oseepta: “base-second”, which is just “second base”.
• bukose: “park-base”, not baseball.
• lartaapta: “ball-first”, irrelevant to baseball as a noun.

Common Pitfalls:
Dragging along modifiers (first/second) or locations (park) that are not part of the requested compound. Stick to the exact stems needed.

Final Answer:
oselarta
