grand

Of great importance, impressive in size, scale, or appearance; magnificent or splendid. This adjective is often used to describe things that are designed to be impressive and awe-inspiring, suggesting an elevated sense of dignity or beauty.

While 'grand' as a noun can informally refer to one thousand units of currency (e.g., 'five grand'), the sense indicated here, with synonyms like 'celebration' and 'event,' refers to a significant, impressive, or elaborate occasion, event, or even a broad concept or scale. This usage is less common than the informal currency term, and it's challenging to capture with a single direct translation, especially in Japanese. This is because the English 'grand' in this context encapsulates not just the event itself but also its inherent impressiveness, scale, and importance, which often requires descriptive phrases rather than a single noun in Japanese to fully convey the meaning and nuance.

• The family celebrated their matriarch's 90th birthday with a grand that lasted all weekend. — This refers to a large and elaborate celebratory event.
• He always aimed for the grand, never content with small-scale projects. — This implies a pursuit of large, ambitious, or significant undertakings rather than minor ones.
• The true grand of her artistic vision was only understood years after her death. — This refers to the profound and extensive nature of her artistic concept or achievement.
