• SynonymグラウンドNeutralLoanword for a sports ground or field, very common in speech, as in 「学校のグラウンド」. 「運動場」 is more written and often appears in school and facility names.
• Synonym競技場きょうぎじょうNeutralA venue built for formal competition, equipped with a track, stands, or even indoors; the emphasis is on sporting events. Not normally used for a school playground.
• SynonymフィールドNeutralLoanword with several senses: a track-and-field infield, the outdoors, or a field of study. For sports grounds it sounds technical; everyday speech prefers 「グラウンド」.

Use 「運動場」 for a sports ground, especially a school playground. In casual talk say 「グラウンド」; 「競技場」 is for proper competition venues, and 「フィールド」 suits track infields or technical contexts.
