@ dropoff yourkeylee - according to Strong's Concordance, the definition used is accurate.
σταυρός staurós, stow-ros'; from the base of G2476; a stake or post (as set upright), i.e. (specially), a pole or cross (as an instrument of capital punishment);
Ultimately, whether or not a patibulum was added to the stake/post/pole upon which Christ was impaled, is not mentioned in the scriptures, nor is it of any importance concerning the Christian belief in Christ's sacrifice.
The topic is perversely elevated to a status of great importance & reverence, to cause animosity/division between certain 'tribes' within Christian denominations - nothing less.
